What I'm looking for

I want to build and ship production agentic AI systems—multi-agent pipelines, RAG, and tool calling—while owning backend reliability in real environments, including security-sensitive deployments, with room to grow engineering depth end-to-end.

I’m an AI and backend engineer focused on building production-grade agentic AI systems powered by large language models. I architect multi-agent pipelines with LangGraph and RAG, grounding responses in domain documentation using vector databases and semantic search.

I’ve implemented tool/function calling through custom MCP servers so agents can interact with APIs, databases, and deterministic business/enterprise logic. In regulated, air-gapped environments, I delivered an end-to-end agentic assistant that connects retrieval, streaming, and live answer generation reliably.

On the backend side, I bring a strong foundation in Python and Java/Spring Boot REST APIs, SQL, and Docker/Kubernetes, with solid DevOps habits like CI/CD and observability. I enjoy bridging AI, backend, and enterprise systems to ship dependable capabilities.
