I build backend systems and infrastructure, with a particular interest in concurrency, scalability, reliability, and performance.

Recent projects include a distributed URL shortener in Go with Redis-backed ID allocation, multi-level caching and load testing; a resilient rate limiter using a Redis/Lua token bucket with an in-memory fallback; and Hostlane, a multi-tenant static hosting platform built with Node.js/TypeScript, Go, PostgreSQL, Redis and Nginx.

I'm looking for software engineering opportunities where I can contribute to building and operating real products, particularly backend and infrastructure systems. I'm open to remote and on-site opportunities.
