About Me
I don't just write code.
I ship products.

I specialize in MERN stack and NestJS, building production-grade applications across healthcare, SaaS, DeFi, and real-time platforms. My work spans the full development lifecycle: architecture, backend APIs, React frontends, cloud deployment, and third-party integrations. I've worked with startups, remote teams, and established businesses across Europe and North America.
