I'm Million : I take full ownership of production systems, ensuring they stay fast under load. By leveraging lean APIs, smart caching, queues, and connection pooling, I scale infrastructure so massive traffic spikes remain predictable, observable, and cost-aware. Still shipping bots and AI features where they belong: on top of solid infrastructure.
- Lean APIs & caching
- Queues & horizontal scale
- Observable & cost-aware
About
I build production systems where APIs, data, and AI meet real users from secure backends and integrations to bots and LLM-assisted flows. I value clear contracts, testing, and shipping responsibly.
Education
Bachelor's in Computer Science
AI & automation
- LLM integration — REST/streaming APIs, tool use, structured outputs, and guardrails for production bots.
- Conversational products — Telegram and web assistants with retrieval-style patterns and clear UX.
- Backend for AI — Nest/Node and Go services, queues, observability, and secure handling of keys and user data.
