Senior engineer who ships — from system architecture to pixel-perfect UI.
I'm a Senior Full-Stack Engineer with 8+ years building high-performance web applications, realtime systems, and AI-integrated platforms. I specialize in React/Next.js frontends and Node.js backends, with deep experience in WebSocket architectures, event-driven systems, and production-grade engineering.
What drives me is the intersection of elegant engineering and real business impact. I've led frontend architecture at enterprise scale, shipped SaaS products from zero to production, and integrated AI workflows into live applications — always prioritizing performance, reliability, and developer experience.
Professional client work and personal side projects I've built and shipped.
