About

I’m a senior/lead full-stack engineer based in Yerevan, focused on building production-grade products across mobile (React Native, iOS, Android) and web (React, Next.js, Node.js). Over the past 5+ years, I’ve owned the full lifecycle of B2B solutions—from UI/UX in Figma to architecture and cloud deployment on AWS, and through App Store/production release with real user feedback.

I specialize in real-time systems, API design, and payment integrations (Stripe), and I’ve also integrated LLM/AI automation into business workflows to reduce manual effort and speed up operations. I enjoy turning complex requirements into reliable software by combining strong frontend/mobile engineering with backend systems (REST/WebSockets, PostgreSQL/Firebase) and pragmatic DevOps practices (Docker, CI/CD).
