What I'm looking for

I seek remote roles building AI‑first, distributed systems that prioritize scalability, developer experience, and real‑time performance, with impact and autonomy.

I am a principal full‑stack engineer with 20+ years architecting scalable SaaS platforms and data‑intensive applications, focused on developer experience and high‑performance UI.

I specialize in React ecosystems, event‑driven backends, and AI/LLM integration, and I have created widely adopted open‑source tools with 30k+ GitHub stars that define frontend architecture standards.

As a technical leader I have led migrations from monoliths to event‑driven microservices, improved scalability and reliability, and engineered real‑time data layers delivering sub‑200ms AI insights.

I found and maintain OSS at Kriasoft, received the GitHub Security Fund, and continuously build distributed libraries and tooling that prioritize performance, type‑safety, and developer ergonomics.
