Tech Lead building high-load, distributed services in Python & Go.
Hands-on with databases (internals & tuning), Kubernetes, Docker and observability; designing systems for scale and reliability.
Currently going deeper into ML & LangChain, and shipping the occasional React / Next.js frontend.
I also write about backend engineering on Habr.
