Summary
👤
Senior🎓
Top SchoolSeán Hanson is an open source developer and full‑stack web engineer with 11 years’ experience delivering production applications using TypeScript, React, Node.js, and MongoDB. He has driven frontend architecture and developer experience improvements at SeatGeek and MongoDB, reducing technical debt through modern migrations, CI hygiene, and test-driven practices. Seán excels at early problem discovery—surfacing edge cases, anticipating user behaviors, and codifying reliable, auditable workflows so teams can respond confidently under pressure. He applies the same discipline to archival and data work, building a large-scale scraping and normalization pipeline for 300k+ records that combines Playwright, Atlas Search, and AI-assisted evaluation. Pragmatic about tooling, he treats AI assistants like Claude and Copilot as disciplined collaborators within documented review cycles rather than shortcuts. Based in New York, he seeks remote, hands-on roles where he can mentor teammates and strengthen systems that scale.
