Rockstar🎓
Top SchoolMark Lewin is a Principal User Assistance Developer with over a decade of experience specialising in developer-focused documentation, API reference authoring, and developer education. He has led documentation and onboarding for complex platforms at Barclays and Oracle, and built developer curricula, code samples and training programs for companies including Ably, Vonage and Shell. Comfortable in "docs as code" workflows, he turns product changes and undocumented features into clear quickstarts, reference guides and hands-on labs across multiple languages and tooling (OpenAPI, Redoc, Spectral). He pairs editorial rigor with practical engineering empathy—having created accredited training, high-quality code samples, and a Pluralsight course used by thousands—which helps teams ship usable APIs and faster developer onboarding. Based in Northampton, UK, he combines enterprise-scale documentation leadership with a background in GIS and curriculum design, making him adept at explaining complex technical systems to both developer and non-developer audiences.
