Hi, I’m Lewis — a senior full stack engineer based in Peterborough, UK, with nine years of shipping production software across automotive, insurance, payroll, and government sectors.

I’ve led engineering teams at IBM, Sopra Steria, and ERGO, architected cloud infrastructure on Azure and AWS, and delivered everything from React SPAs and Next.js platforms to serverless backends and real-time data pipelines — always with a focus on code that’s fast, secure, and built to last.

Currently contracted to ADP on their flagship RUN payroll platform. I’m open to my next senior or lead role — remote, UK or EU — whether freelance or permanent.
