John was high signal and was able to get engaged on our environment and working with our staff to strategize on email security changes.

John was exceptional to work with. He quickly understood our business needs and brought a level of clarity, organization, and technical depth that immediately improved our IT environment. He helped us successfully set up and secure our Microsoft 365 infrastructure, provision domains, implement strong email security, and harden the overall Microsoft ecosystem in preparation for growth. What stood out most was John's ability to translate complex technical decisions into clear, practical guidance. He was responsive, proactive, and always focused on long-term stability rather than quick fixes. His work significantly strengthened our systems and gave us confidence that our technology foundation is built correctly for scale. I highly recommend John to any organization looking for a highly skilled, trustworthy IT advisor who can both architect and execute at a very high level. Working with him was a great experience.

John was an excellent freelancer to work with. We were having a multitude of email deliverability issues. He immediately offered solutions and effectively troubleshooted our issues. Our request was for him to inform us what to look for in the future and he was an excellent teacher. We will happily work with him again in the future.

Huge help yet again. This is the second time John has helped up with the #1 important aspect of our service: deliverability. Highly recommend, and I'm sure we will work again in the future. After helping us diagnose the issue, he gave us actionable steps to solve this problem. He also gave us access to some great insights and new tools for deliverability. Thank you John.

John was a great communicator in terms of speed and the level of detail he provided. Overall great communication, response time, speed, ideas, and billing was fair for the service provided.

John is always fast, straightforward, and easy to work with. His communication, availability are awesome. I feel like the minute I have an issue I contact John and it seems like its done. Highly recommended.

Third or fourth time working with John. Will definitely hire again.

Excellent communication. Very timely in his work and responses to any and all questions. This was my first time using Upwork and he really helped me feel comfortable and educated throughout the process. Will definitely be reaching out to John again for future jobs we need!

John is the first person I've hired on Upwork who works harder than I do. Day or night, rain or shine, John was there to manage and execute on a complex migration project under time pressure. He asked great questions (read: asked from experience or did his research prior to asking to save us time) and always followed through on his recommendations that were accepted. 10/10 would recommend.

John was incredibly responsive and brought strong email expertise to the table. He jumped in right away, offered clear guidance, and made the process & resolution smooth and efficient.

We've engaged a number of professionals through Upwork. I can confidently say John's the best professional we've ever engaged. We brought him a large project and a big challenge - to help us not only improve our results with email set-up, deliverability, optimization, and measurement (across hundreds of campaigns/programs), but to teach us how to become experts in these topics ourselves. John was organized, thoughtful, proactive, engaged responsive, timely, and an expert in his field. The best combination of know-how, expertise, and team-based collaboration. He always went above and beyond. and showed genuine interest and investment in our results and progress. He helped us accomplish every one of our goals and measurably improved our results. We're delighted to have had the chance to work with John, and would unreservedly recommend him to others.

John was perhaps the most professional & most responsive consultant I have yet found, during my years on Upwork. He gave me 100% of his focus and finished my project under the estimated time and budget. HIGHLY RECOMMENDED.

John did a great job asking questions and helping us determine if there's a problem. Very honest and knowledgeable!

John was awesome to work with. Communication was great, extremely knowledgeable, and, a true expert in his field. Will 100% plan to use John in the future.

John is an absolute pro when it comes to email deliverability. He quickly pinpointed my issues, offered clear and practical solutions, and very patiently guided me every step of the way.

Highly recommend him if you want real results.

Knowledgeable. Thoughtful. Fast. Clear. Responsive. Good natured.

John was super to work with and very flexible with meeting times, and trustworthy. He always responded right away, and was very good about double checking his work and working very conservatively when migrating email accounts, so as not to ever be at risk of losing any of our files. Will definitely use him again for our IT needs.

Second time working with John. This time we had an email spam issue. He was quick and professional as always. We will continue working with John as things come up.

John solved networking problems spanning several platforms (Google Workspace, Meraki, Wifi) with me in real-time. It was quick. Job well done. I would definitely use John's services again.

John did an excellent job on our email deliverability audit. He was knowledgeable, thorough, and professional throughout. His analysis covered everything from DNS records (SPF, DKIM, DMARC) to content and list hygiene, with clear, actionable recommendations. Thanks to his insights, we quickly resolved several issues and improved inbox placement. Communication was prompt and helpful. Highly recommend if you're looking for an expert in email deliverability.

John was fantastic, he gave us solid advice. Would be an honour to hire him again should we have a need for emailing advice.

John was very friendly but also very solutions-focused. The moment we got started he gave his full attention and took the project straight to the finish line. I was especially happy with John's thorough and prescriptive write-up. We'll definitely return!

John was great to work with and very responsive, as usual! This is the fourth or fifth time we've worked with him :-)

John was incredibly fast and professional. I needed to switch my primary domain for our Google Workspace (Gmail, Drive, everything,) since we just purchased a new domain, and he knocked it out in an hour. No issues. Will use John again.

John provided fantastic work on short notice.

An absolute genius. I haven't seen someone so knowledgeable, honest, responsive, and fast! I rehired John again and will be using his services exclusively. I'm utterly impressed with him and his work ethic. Highly recommended!

John was EXCELLENT at providing our agency the IT support we needed. As a small agency with no IT department, it was critical we had an expert helping us make the transition when we completely rebranded. John held our hands through the entire process, ensuring all of our accounts were set up properly and securely. We truly could not have made this move without him! If you are looking for an absolute pro to help manage any IT work your company may need, go with John. Not only does he really know his stuff, but he was incredibly communicative the whole time, chatting with our team via Slack (and even staying in there a few weeks after the project was complete to ensure there weren't any questions or issues anyone was encountering). He was a true pleasure to work with. Really glad we found him and were able to complete this project so successfully and without any headaches. Thank you John!

John did an exceptional job helping me improve our email security and manage complex conditional access policies.

I highly recommend working with him.

John has been an incredible help to my business and team. He not only thinks outside the box to find solutions but also is extremely fast to respond, exceeding my expectations. John may have been overqualified for the original projects I needed help with, but I am thrilled with the result and he was worth the investment. He has continued to help with IT and technology connections as they pop up (so many apps to connect!) and I can always trust for him to take on the task and get it done well before it's due date. I highly recommend John and look forward to using him on future projects.

John has been a dream to work with. Super knowledgeable and always available when we needed him. Very responsive and across everything we needed. I would definitely work with him again.

John has been an invaluable asset to our team, ensuring our IT operations ran seamlessly. His dedication and commitment are truly unparalleled. Not only is he highly knowledgeable, but he also consistently goes the extra mile to ensure everything is running at its best. If you're seeking a top-notch IT Admin consultant, look no further than John. Highly recommended!

I am SO grateful I found John. I am the owner of a boutique Corporate Event Planning Company for 21 years now and desperately needed to upgrade our email platforms. We decided to migrate all emails onto Google Workspace as well as begin using Google Drives. Let me say, I do not like change and was very nervous at the thought of this process. But, from the moment I spoke with John he put my mind at ease. I trusted him immediately. Not only did he migrate all our emails with ease and no disruption to our day to day business, but he also taught us how to use Google Drives and other features. He also went above and beyond to teach me so many other ways to work more efficiently and is always there to answer our questions. John is a wealth of knowledge, a stand up guy and a super nice human. Needless to say, he is now our official Tech Guy. I cannot recommend John enough. - Beth L.

John fixed my months long email/spam folder nightmare in a matter of hours. John was especially proactive and an amazing communicator. I already have plans to hire John for another project! Yay, John!

John is a talented, well versed Google Workspace Admin. A pleasure to work with and straight to the point.

John D gave himself fully to this project and stayed with it until completion. I highly recommend to anyone!

Honestly we haven't found a problem he hasn't been able to solve for us. He's extremely responsive and handles issues as quickly as they arise. I definitely intend to work with John again.

John was by far the most knowledgeable guy that I spoke to. He was massively responsive, evenings, and weekends included. Plus, he was a great guy to work with. I highly recommend him!

John was very helpful and particularly communicative. We really appreciated the follow up after the consultation. He clearly cares about the result and truly supporting his clients!

Great working with John for the second time! He's clearly a professional and works tirelessly to fix whatever issue you may be experiencing.

In my extensive career of over 10 years, I've seldom encountered a professional as remarkable as John.

John has done multiple jobs for us and has always exceeded expectations.

John was patient, helpful, extremely knowledgeable, and he solved a problem that had been plaguing us for some time and was important to our operation. He diagnosed the problem quickly and got the job done, despite several system glitches (no fault of his).

John is extremely knowledgeable and professional. He is really easy to work with and goes above and beyond.

Working with John was a dream! I hired him to work on a domain switch in Google Workspace for our nonprofit as part of a rebranding project. I could not have been luckier to find John. His expertise is unparalleled, he is trustworthy and personable, and he truly cares about the work. John was quick and easy to communicate with and made sure I understood each part of the process. The domain switch was seamless, and he even identified and fixed some deliverability issues with our DNS settings that I wasn't even aware of. Not only did we accomplish what we set out to do with John, but we are in a better place because of his expertise. There are many options out there at a wide range of rates, but hiring John is 100% worth it - you truly do get what you pay for. I truly look forward to working with him again.

John D. was very good in helping assess our company needs and also helping to set them up to achieve our goals. He was readily available, and very knowledgeable. We were very happy with his professionalism and ability to get done what we needed. Friendly, and courteous. Would recommend.

John is great to work with. I was needing some urgent help/support with DNS settings for a domain. He jumped on a Zoom call with me right away and helped answer the questions I had and even recommended some further steps outside of my initial questions to ensure that my domain and email marketing worked properly. I would highly recommend him and will definitely be working with him again in the future!

John did a great job of jumping in and helping us identify issues with our Outlook. He was able to identify the issue and took the initiative to reach out to previous contractor to resolve.

John was extremely knowledgeable and easy to work with. His expertise allowed for a successful project.

John is an exceptional freelancer who went above and beyond to provide exceptional service and communication throughout the entire process. I was extremely apprehensive about hiring someone remote to conduct our data migration for Gsuite, but a background check on John and some history of his services eased my mind and gave me the confidence to move forward in working with him. A man of his word, he over-delivered when the initial agreement ended up being more work than what he had initially anticipated. If John's skillset meets your needs I'd highly recommend him.

John is a Rockstar! Thank you so much for your quick review and even faster resolutions. 5 stars form our firm!

John is amazing--gets the job done right the first time. John is always available and goes the extra mile to make sure the client is satisfied. John has the technical knowledge and interpersonal skills to understand and solve difficult problems. My company has been developing software since 1998 and I have hired many consultants in IT and engineering. I will not hesitate to contact John for all our future IT tasks. We had a fixed contract but he spend extra time to test and secure the systems. I gave him a bonus for his fine work that was above and beyond.

John is exceptional. He communicates extremely well, followed through on everything he said he would do, solved every issue, and quickly established rapport and trust with me. Our project was not the most complex or large in scope, but he fully migrated us to Google Workspace and we now feel more organized, focused, and confident in our systems. I now consider John our "IT Guy" going forward, and could not have had a better experience working with him via Upwork. Thank you, John!

John listened carefully to what we needed and once we were in sync he went right to work to solve our problem. He was fast and efficient. Going overboard to ensure we were satisfied with our results. We plan to use John again and highly recommend him to others in the meantime. Thank you.

Excellent and immediate support. Determined our problem and provided alternatives. Will be our go-to person for Google Workspace and Chromebook support.

John was knowledgeable, efficient and a great communicator. I look forward to hiring him again as my go-to expert for all things Google Workspace.

John was awesome! I have a small but growing business and I did not have time nor the knowledge to set up the infrastructure for my team. He was very responsive, even when I needed something last minute. I would definitely hire John again. On top of it all, John was a very nice guy. Great experience overall!

John is fantastic. When you turn over the keys to your business email and accounts it comes with a certain amount of stress and worry. John quickly showed he was trustworthy and professional. John knew exactly what to do and how to do it. His communication was excellent and even went above and beyond making recommendations to improve our security, backups, and workspace. John came in under my budget and communicated the entire time to make sure I was aware of the status of the migration and what to expect next. I will keep John in mind for future projects and when the unexpected comes up.

John is an EMAIL MAGICIAN!!! I've been in the email game for 15+ years .... John is good, VERY good. Will be working with him from here on out for anything email related

John was extremely responsive and thorough in responding to my issue. I had a major issue with my emails ending up in my recipient's spam folders and it was very disruptive to my business. John went to the ends of the earth to track down the issue(s) and resolve them appropriately.

John is powerfully capable of helping with the greater Google ecosystem. I needed help with setting up Youtube properly and he left me with enough working knowledge that allowed me to grow. Plan to use him next to assist with Google Workspace. Thanks!

John was professional, responsive and knowledgeable. Happy to work with him again.

Excellent experience. John was very dedicated to solve the task for us. Thank you very much!

I would highly recommend using John! John helped me migrate my company's entire email system from Godaddy to a corporate Google Workspace. John was highly responsive and a great communicator. He worked into the evening to make sure that if there was any downtime between cutting the email over from GoDaddy to Gmail, that it would be after afters (there was no downtime!). John stayed with us after the migration to make sure we understood how to use Google Workspace and the corporate email administrative features. John is incredibly talented and knows email and IT admin like the back of his hand. Coupled with this customer service, John is one of the better IT professional experiences I have had in my 20-year career.

John did a great job helping me out of a jam with my gmail account, that's twice now! He knows what he is doing. Highly recommend!

John's picture must be next to the word persistence in the dictionary. He left no stone unturned in finding a solution to my deliverability problem. Many would have given up long before, and people I hired before him insisted there was nothing they could do. But John went down every rabbit hole until he found a solution. I highly recommend him for any issue, large or small, involving email deliverability.

John is a fantastic communicator and qualifies as an expert in his field. He's a rare find and easily exceeds a 20x benefit to cost ratio. You'll know you picked the right guy the moment you get started with him. We've worked on a few projects together and he consistently surpasses our expectations!!

It's always great to work with John!

Back with John again for a new project. He is very competent and efficient. Most importantly to me, he's always happy to help and does a great job.
