About Hossein Khalili

I'm a senior frontend engineer for complex production web applications — crypto and fintech exchanges, multi-role e-commerce, AI chat, dashboards, admin tools, and real-time surfaces.

Since 2018 I built production frontends as a freelancer, primarily with React and Next.js. Since January 2026 I have been a full-time remote frontend developer at barman-tech. I often own frontend implementation on demanding products, alongside other tech and design teammates. I prefer clear structure and maintainable state over buzzwords.

I'm comfortable with WebSocket, REST APIs, and libraries like Redux and Zustand. I'm building with NestJS on small practice projects — learning the backend path, not claiming a shipped production backend.

Bachelor of Software Engineering — HADAF University of Mazandaran (2015)
