What I'm looking for

I want to build production-grade automation, backend services, and AI agent systems (MCP/RAG) that improve reliability and observability. I’m happiest solving complex problems end-to-end—designing clean systems, integrating APIs, and reducing incident response time.

I’m a Python Developer with 5+ years of experience building automation systems, ETL pipelines, and API integrations, with a strong focus on clean, production-grade code. I pair backend development with high-availability infrastructure and observability, including monitoring 150,000+ metrics across enterprise environments.

As an AI Agent Engineer, I’ve integrated LLM APIs and practical RAG pipelines using MCP (Model Context Protocol), OpenAI, and Ollama—helping teams ship AI-assisted tooling in real operations. I also architect incident workflows and intelligent alerting (Zabbix + Grafana), and I’m actively extending these ideas through personal projects like an MCP-powered Shopping Agent with a local ChromaDB + sentence-transformers search pipeline.
