Bryce Sayers-kwan is a senior full-stack software engineer with nine years of experience building production web and decentralized applications and scaling engineering teams. He has repeatedly defined stacks and base architectures for new product lines, from launching a crypto payments platform as the sole engineer to spearheading Ecosystems Apps and AI observability systems. At Prove AI he rescued off-track work by rebuilding a critical codebase solo, then grew the team from 3 to 12 while leading hiring and interview design. Bryce combines hands-on implementation (TypeScript, React, Node, PostgreSQL, Docker/Kubernetes) with pragmatic systems thinking—creating auth systems, 2FA, and large-scale data pipelines that reduced multi-day jobs to hours. He mentors junior engineers, designs onboarding and interview processes, and has a habit of shipping high-quality proof-of-concepts to de-risk product decisions. Based in Lisbon, he pairs startup grit with process discipline to deliver auditable, scalable solutions.
