Top SchoolAlexander Joo-Hyun Sullivan is a full-stack software developer and bioinformatician with 10 years of experience building production web apps, developer tools, and scientific data visualizations. He currently develops software at Verily after leading end-to-end engineering for Masterpiece X, where he launched a generative-AI 3D model pipeline, managed CI/CD, and integrated VR workflows for Meta Quest. His background in life sciences (MSc, University of Toronto) underpins a track record of creating research tools—like the eFP-Seq Browser and GAIA—that combine frontend UX, backend services, and statistical/NLP pipelines to make complex biological data searchable and usable. Comfortable across TypeScript/Node/NestJS, React/Next, Python, and Unity/C#, he emphasizes test-driven development, analytics-driven product decisions, and accessibility. Colleagues know him for bridging lab-grade reproducibility with consumer-facing product polish and for mentoring cross-functional teams to deliver high-impact tools on tight timelines.
