About

Software engineer focused on web and mobile products. React Native / Next.js · TypeScript / Node · Clean Architecture. Worked on Morning Consult Pro with a Washington D.C. team serving 1M+ users, and now runs Overzone, my software studio, where I built DataRow, an internal AI-agent platform.

Background

I've worked on production software for 4+ years — first as a React Native engineer at Salvus, where I helped rebuild an offline-first healthtech app used by 30k+ professionals and cut data sync from 3 minutes to 1 second. After that, I joined Morning Consult Pro and delivered 20 features with a Washington D.C. team, on a platform with 99.99% uptime and 100% Jest coverage.

In parallel, I run Overzone, my software studio. We've delivered 12+ products and manage 50+ sites & systems. I also built DataRow, an internal AI-app platform with Holmes, a custom agent harness.

I care about practical engineering: performance, infra cost, clean architecture, and code other people can work with. A $0.26/month redirect system serving 1M+ users is the kind of result I like to aim for.
