Who I Am
Senior Technology Lead focused on Generative AI and LLMOps, with a strong background in enterprise software engineering and delivery. I lead a team responsible for the production reliability of an enterprise AI (LLM) gateway — the platform through which business applications access large language models. Alongside operating that platform, I build hands-on with GenAI: RAG pipelines, agentic workflows, and Model Context Protocol (MCP) tooling. My foundation is full-stack development (.NET, MEAN / MERN) and cloud-native delivery on AWS and Azure.
My Approach
I bring enterprise engineering discipline to AI systems — reliability, guardrails, cost-awareness, and observability over hype. I favour clean, maintainable code, CI/CD, and pragmatic architecture decisions, and I care about building systems that hold up in production, not just proofs-of-concept. Having led delivery and mentored engineering teams for years, I spend as much time guiding people and design choices as writing code.
