About Me

I'm an AI & Data Engineer with 6+ years building critical-scale infrastructure — from processing 8 billion events/day for UK Critical National Infrastructure to designing LLM-powered workflows for telecom and supply chain at Elisa Polystar.

My focus sits at the intersection of GenAI, LLMOps, and distributed data systems — turning experimental AI into production-grade pipelines that actually scale. Currently building innovative prototypes at Colab Foundry.
