What I'm looking for

I'm open to remote roles where I can ship AI/LLM features and high-load backend systems into production.

At Kwork, I design and ship production RAG systems using Qdrant and OpenSearch, with dynamic routing across three LLM providers. My work cut response time by roughly 3–4× while supporting 25–35k tasks per week.

I build high-load services in PHP, Laravel, Go, and Python, from architecture through launch. I’ve also led teams of 5–10 engineers and introduced code review, CI/CD, and engineering standards.
