Summary
👤
Senior🎓
Top SchoolOllie Bannister is a London-based founder and full-stack software engineer with a decade of hands-on experience building product-focused web applications across startups and SMEs. He specialises in TypeScript/React on the frontend and .NET/C# on the backend, but routinely explores other stacks to solve practical problems. Self-taught from an early age and grounded by formal bootcamp and computing studies, he progressed from frontend specialist to senior engineering and team lead roles at Raygun and StudySpy. He combines product sensibility with engineering rigor, often wearing multiple hats from architecture to shipping features. An enduring curiosity — sparked by his first program on a family Dell at age 11 — drives him to pursue projects that push technical and UX boundaries.
