Go Backend & AI Engineer in Astana, Kazakhstan

I'm Zhandos, a backend and AI engineer based in Astana, Kazakhstan, working remotely with teams across Europe and the US. I build high-load backends in Go, Telegram bots, and AI-powered systems.

Day-to-day stack: Go, PHP / Laravel, Python, PostgreSQL, Kafka, Docker and Nginx. A large part of my work is LLM integration — wiring Claude, Qwen and DeepSeek into real products, automating workflows and building internal developer tools.

Everything listed on this page runs in production and serves real users: an AI Gateway, TimeGate (QR-based attendance tracking via Telegram) and a logistics bot.

I work in GMT+5, which overlaps comfortably with European hours, and communicate in English, Russian and Kazakh. Reach me on Telegram or LinkedIn.
