Will has deep experience standardizing developer workflows and infrastructure for data- and finance-focused teams, and a track record of shipping end-to-end systems from Electron browsers to React Native apps. Passionate about developer tools and collaborative software, he brings entrepreneurial grit and a research-minded approach to building resilient realtime systems.
