Building high-load backends, AI-powered systems, and developer tools from Astana. Turning complex APIs into elegant solutions.
Systems that handle real traffic, process real tokens, and solve real problems.
Unified OpenAI-compatible proxy for Claude, Qwen, and DeepSeek. OAuth token rotation, streaming, usage tracking, and a live telemetry dashboard. The system you're looking at right now.
Workplace attendance tracking. An office station shows a signed QR code that rotates every 10 seconds; the employee scans it in Telegram and the check-in is proven — no photos, no buddy punching. Reports on hours and lateness.
Open live site →Telegram bot for a China-to-Kazakhstan shipping company. Four steps and the client gets a personal warehouse code. Admin panel manages cities, 26 pickup points and message templates. Live: serving real customers.
Telegram Mini App for personal finance tracking and task management. Full-stack: Go backend with webhook processing, embedded web UI.
View on GitHub →High-throughput bridge between HTTP APIs and Apache Kafka. Accepts REST requests, routes messages to topics with guaranteed delivery.
View on GitHub →Automated data collection system. Two implementations: high-performance Go version and Python prototype with async processing.
View on GitHub →The three things people come to me for most often. Each one is backed by projects already running in production.
Bots and Mini Apps for sales, support and internal workflows. From a simple order form to a full admin panel with roles and reports.
Discuss a project →Wiring Claude, Qwen or DeepSeek into a product you already run: assistants, document processing and automation of daily routine.
Discuss a project →Services that hold real traffic, plus integrations with payment systems, CRMs and external APIs — built to survive load and failures.
Discuss a project →The tools I reach for daily. Backend-heavy, AI-augmented, infrastructure-minded.

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.
