About

Engineer first.
AI-native by practice.

Backend Engineer and Tech Lead specialising in scalable API platforms, microservices, and production-grade agentic AI systems. I build multi-agent workflows, LLM orchestration pipelines, and RAG-powered tools that turn AI capabilities into real business automation — in Python (Django, FastAPI) and Go (Fiber). I integrate and self-host open-source AI infrastructure, including local Hermes LLM deployments, into production social and marketing automation. I lead cross-functional teams, own architecture decisions, and ship at speed.

The through-line in my work: turning AI capabilities into automation people actually run. Agents get explicit, inspectable workflows; retrieval gets grounded, source-aware answers; and the unglamorous parts — task queues, orchestration, deployments — get treated as features, because in production they are.
