About
I am a Backend & Systems Engineer based in Astrakhan, Russia. I design and build backend systems, Linux services and infrastructure that run reliably in production.
My focus is on non-trivial problems — automation, domain infrastructure, background services, Telegram integrations and custom APIs. If you need something that “just works” 24/7 without constant manual control, I can design and implement it end-to-end.
