What I'm looking for

I’m looking for a team where I can own architecture, ship hard production problems end-to-end, and measurably improve speed and reliability. I work well across time zones (US/EU overlap), mentor others, and move fast with strong engineering standards.

I’m a Senior/Lead Flutter engineer with 8+ years shipping production mobile, web and desktop products, and the Dart backends behind them. As one of just two core engineers, I’ve owned end-to-end development of an AI app builder—owning architecture, key technical decisions, code review, and mentoring across a 7-8 person remote team.

I gravitate to hard, complex problems others avoid, and I focus on measurable reliability and speed. I led the initial architecture and front-end build from MVP, designed a single codebase powering desktop, web, and cloud modes, and cut debugging/investigation time 70%—while spinning up new servers 3× faster through backend and CI/CD automation.

On the product side, I’ve scaled live-preview capacity from 65K to 200K sessions and improved load times up to 6× faster by building an on-demand app-preview engine and tuning global CDN caching. I also bring depth across Flutter architecture/testing and backend/infrastructure (Protocol Buffers, REST/WebSockets, OAuth integrations, Docker/Nginx/Cloud Run), plus a strong open-source background with widely used Flutter packages.
