Over mij
I build AI agents that go into production, not demos. My focus is LangGraph agent workflows, RAG-based retrieval, and LLM integrations (OpenAI, Gemini, MCP) that plug into your systems and hand off to a human when needed.
Before AI, I spent 8+ years building secure, high-scale backend systems (Java, Spring Boot, AWS, Kafka) for telecom clients. That shapes how I build agents: durable task queues, tool execution, and clear logs for recovery.
I work directly with you, no account managers, and leave you with code you can maintain.
