What I'm looking for

I’m looking for roles where I can own end-to-end architecture, ship production React/React Native + Node.js products, build design systems and performance-critical experiences, and apply AI/real-time tech with a team that values engineering rigor.

I’m a fullstack engineer with 11 years shipping production React, React Native, and Node.js applications across fintech, healthcare, e-commerce, and AI. I’ve led teams of 6–8 engineers, owned end-to-end architecture, and personally built 20+ products—from design systems and real-time dashboards to sub-200ms voice AI agents.

I adapt fast across stacks (React, React Native, Angular, Next.js, Node, Express, TypeScript) and focus on scalable delivery: reusable component standards, performance optimization, and reliable REST APIs. Recently, I owned frontend architecture at Jiffy.com and led contract engagements at Toptal, building voice agents and session-persistent LLM chat experiences.
