Michal Koper

@michalkoper

I build production full-stack products, RAG systems, and scalable cloud infrastructure.

What I'm looking for

I'm looking for senior IC or tech-lead remote contracts where I can own end-to-end delivery of production full-stack, cloud, and LLM systems.

I've built products including Fightime.tv, VerifyStock.com, Interim Robots, HookSync, and Tivod, owning architecture, APIs, infrastructure, payments, and production delivery. My work spans Rust, React/Next.js, TypeScript, Python, AWS, PostgreSQL, Redis, and Stripe.

Previously, I led Cloudflare WAF and CDN migration for 200+ Natural Pharmaceuticals web properties with 99.9% availability, and built Django/AWS educational platforms serving thousands of concurrent users. I'm focused on production LLM systems with hybrid RAG retrieval, evaluations, Row-Level Security, audit trails, and enterprise-grade safeguards.
