André Cruz is a Principal Architect based in Porto, Portugal with 14 years of experience designing and shipping full-stack web platforms and developer tooling. He currently leads architecture at Uphold, applying blockchain and payments knowledge to scale a multi-asset financial platform used worldwide. Previously a CTO and lead engineer, he combines hands-on JavaScript expertise with system-level thinking—authoring fixes and features across popular open-source projects like bower and cross-spawn. His contributions span front-end UX polish (rangeslider.js) to backend compatibility and testing improvements, reflecting a pragmatic focus on reliability and cross-platform behavior. Comfortable moving between product and infrastructure, he also mentors teams and has a master’s in Computer and Telematics Engineering. A detail often overlooked: he has repeatedly improved test suites and examples to make libraries more usable for other developers, not just core functionality.
