About

I'm a Software Engineer with 5+ years of experience building and scaling web platforms. Currently at Sitgram, working on Turborepo monorepo architecture and type-safe microservices with oRPC.

Previously at Yupsis and Shunno IT, I built edge AI pipelines on Cloudflare Workers, real-time IoT event processors, and commercial ERP/inventory systems. I care deeply about clean system design, developer ergonomics, and high-reliability infrastructure.
