Rockstar🎓
Top SchoolColin Rotherham is a senior Frontend Developer with 14 years’ experience specialising in JavaScript, Node.js and web performance, currently delivering accessible government services from Poynton, UK. He combines a designer’s attention to interaction details with backend skills in microservices and serverless patterns, having built high-performance, WCAG-compliant applications that score 100/100 on Lighthouse. A regular contributor to prominent GOV.UK open-source projects, he’s helped harden components for IE11 compatibility and improve accessibility testing using puppeteer/axe tooling. He’s equally comfortable optimizing browser latency and architecting secure session and queueing integrations in Node.js, and runs his own consultancy, Colin Rotherham Design Ltd., alongside public-sector roles. Unusually for a frontend specialist, he pairs deep accessibility expertise with hands-on backend engineering and developer-experience improvements.
