I build AI-powered applications, real-time systems, and scalable backend infrastructure that developers and businesses can use in production.
Most of my work is hands-on: designing backend architectures, optimizing APIs, building event-driven systems, and integrating AI into real-world products.
currently working in AI agents, LLM observability, distributed systems, and backend engineering.
- Full-stack applications — end-to-end product development with Next.js, Node.js, and TypeScript.
- Distributed systems — event-driven architecture, Kafka, Redis, and real-time communication with WebSockets.
- AI-powered products — LLM integrations, AI-assisted workflows, and intelligent applications.
- Backend performance — API optimization, caching, database performance, and load testing.
- Developer tools — building practical tools and infrastructure that make developers more productive.
