Work
Five engagements. Real stakes.
Each of these had something on the line — a live attack, a collapsing sender reputation, a migration that couldn't break. Four are named; one is under NDA. They're what we'd point to if you asked what the work actually looks like.

John is a true professional and an absolute expert in email deliverability. His understanding of SPF, DKIM, DMARC, and advanced routing inside Klaviyo was exactly what we needed. He didn't just fix the issues — he built systems that continue to monitor and improve deliverability across platforms.
OOliverCEO, Curative Mushrooms 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 and always followed through. 10/10 would recommend.
FAFred A.Abelian Group John is amazing — gets the job done right the first time. Always available and goes the extra mile. 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.
