Senior engineer who owns problems end to end.
I'm a Senior Full Stack Developer with years of experience architecting and shipping SaaS platforms, AI-driven applications and payment infrastructure alongside US-based product teams.
I own complex problems end-to-end, from database design and API architecture to frontend performance and production monitoring. I've built systems serving 100+ concurrent users at sub-50ms response times with 95% Redis cache hit rates, integrated Claude and OpenAI with structured outputs, and rolled out multilingual experiences at scale.
My day-to-day is .NET Core, React, Next.js, and TypeScript, but I'll reach for whatever the problem actually needs: WebSockets for live preview, iTextSharp for dynamic PDFs, Stripe for subscriptions, a custom MCP server for AI tooling.
