About

I’m a developer who specialises in AI-integrated software architecture and legacy system modernization from a foundation of over 25 years in the Microsoft technology stack. I bridge the gap between robust, enterprise-grade engineering and the future of Generative AI, specializing in C#, .NET 8, and Python-based LLM frameworks.

What differentiates me from other developers is my dual-threat capability: I possess the deep architectural “scar tissue” of a Technical Lead who has managed teams of 8+ senior developers, combined with the hands-on agility of an AI Engineer proficient in LangChain, RAG, and CrewAI. I don’t just write code; I transform businesses—whether by slashing technical debt by 85% or architecting digital strategies that directly improve ROAS and operational efficiency. My sector experience is vast, spanning high-end hospitality, digital media consulting, and prestigious sports organizations like the AELTC Wimbledon Championships.
