Professional Overview

I'm a hands-on AI engineer and technology leader who loves solving difficult problems and turning new technology into something genuinely useful. I particularly enjoy working with LLMs and agentic AI, exploring what these systems are capable of and figuring out how to make them reliable enough for real-world use. Most recently, I worked as a Senior Applied AI Engineer at Zapier, building AI infrastructure, agentic systems, evaluation frameworks and model training pipelines. Before that, I founded Execify.ai, where I designed and built an AI platform to automate everyday work for executive teams. My background is in software development, DevOps and cloud infrastructure, and I've also spent several years in customer-facing solutions architecture. I enjoy getting stuck into the technical details, working with talented people and finding practical solutions to complex problems.
