AI Engineer London
Production AI engineering - building systems that survive real users, real data, and real scale.
As Associate Director of Applied AI/ML at Fitch Ratings, I design and build production AI systems daily - from agentic workflows to RAG pipelines to LLMOps infrastructure. This is not research; this is engineering that ships.
I work across the full stack: Python and FastAPI for backend services, LangChain and LangGraph for agent orchestration, React and TypeScript for interfaces, and AWS/Azure for deployment. Every system is built for reliability, observability, and maintainability from day one.
What I Build
- Agentic AI systems using LangGraph and multi-agent orchestration
- RAG pipelines with vector databases, embeddings, and reranking
- LLMOps infrastructure for prompt versioning, evaluation, and monitoring
- Production ML systems for financial analytics and regulatory environments
Engineering Approach
I care about the whole path from prototype to production: model choice, orchestration, APIs, deployment, observability, and the developer ergonomics around it. Every system must be operable by a team, not just its builder.
