Summary
🤩
Rockstar🎓
Top SchoolWillow Chargin is a Senior Software Engineer in Seattle with 13 years of experience building full-stack systems and developer tools, currently focused on access control at Google. Their background spans applied robotics platforms—instrumenting fleet, spatial, and real-time telemetry for Carbon Robotics’ LaserWeeders—to developer-facing ML tooling on TensorBoard, where they improved frontend data-provider integrations for a widely used TensorFlow visualization. A co-founder of SourceCred, Willow blends product-minded engineering with community-oriented open-source work, adding UI and API improvements that helped the project measure and reward contributions. Comfortable across frontend and backend stacks, they favor pragmatic, test-backed refactors and bring a quietly opinionated engineering style (their GitHub bio even gives the phonetic pronunciation of their name).
