Harry Nicholls is a pragmatic Fractional CTO and senior software engineer with over a decade of experience building scalable web and blockchain products using TypeScript, React, Next.js and Go. He has repeatedly combined hands-on delivery with technical leadership—re-architecting platforms to cut AWS costs by 61%, rewriting critical services to achieve 18x performance improvements, and shipping on-chain tooling including an ERC-721 deployment. Comfortable across e-commerce, finance and web3 domains, he designs end-to-end systems, leads product engineering organisations, and mentors teams while introducing Agile and testing rigor. His background in chemistry and early work in analytic consulting inform a data-driven, methodical approach to problem solving. Based in Richmond Hill, Ontario, he balances strategic roadmap work with active engineering, frequently taking on the toughest technical refactors himself.
