Senior🎓
Top SchoolWilliam Okafor is an engineering team lead based in London with nine years of experience building scalable web and payments platforms across startups and fintech. He combines hands-on backend and API design work—ranging from converting monoliths to microservices to building OTP and webhook systems—with product-facing leadership at Velocity Black within Capital One. As a former founder and early engineer at cross-border payments startup Waza and GetEquity, he brings entrepreneurial grit and a strong grasp of integrations with third-party payment rails. Known simply as a "Builder" on GitHub, he favors pragmatic, domain-driven architectures and clear public APIs backed by real documentation. Colleagues describe him as a technical coach who partners closely with product and design to deliver high-impact features while instilling best practices. He’s as comfortable shipping low-level integrations as he is shaping team strategy to scale luxury lifestyle and fintech products.
