What I'm looking for

I'm looking to build production AI systems where agent reliability, latency, cost, safety, and correctness are treated as core engineering problems.

At Iceberg, I build production LLM agents in Python and LangGraph for a UK proptech platform serving 1,000+ estate agencies and 10,000+ end customers. I've shipped client-facing sales and listing analysis agents, a codebase-grounded engineering assistant, and safety guardrails for agent tool use.

Before Iceberg, I built domain-specific AI agents and Go services at Virtus ARGE, including a physiotherapy symptom analysis agent that reached 92% accuracy. At Gamer Arena, I helped migrate 68 services from Node.js to Go and owned resilience testing across backend services; I’ve also shipped 11 AI and backend projects to production, from multi-agent orchestration and observability tooling to a live social fitness platform.
