San Francisco, California, United States
Summary
👤
Senior🎓
Top SchoolThomas Deegan is a seasoned software engineer and founder with 12 years of experience building production-grade systems in San Francisco, currently co-leading Meter App. He specializes in lidar perception, 3D computer vision, robust sensor fusion, curriculum and multi-task learning, and data engineering—skills he applied to scale Waymo’s perception stack to support 250k commercial trips per week. Before that he helped Cruise’s computer vision team and contributed to cross-platform compiler toolchains at Google, including notable work on J2CL and the Closure Compiler (improving devirtualization, source maps, and runtime emulation). Thomas blends research-grade model design (Lift-Splat-Shoot, Sparse Window Transformers, multi-view fusion) with pragmatic production engineering like auto-labeling, active learning, and distillation. He’s equally comfortable shipping low-level compiler optimizations and leading end-to-end perception pipelines, and his background suggests a knack for translating cutting-edge research into robust, scalable systems.

Java to Closure JavaScript transpiler
Role in this project:
Back-end Developer
Back-end DeveloperContributions:136 commits, 1 PR in 3 years 2 months
Contributions summary:Thomas primarily contributed to the Java to Closure JavaScript transpiler, focusing on implementing and refining core functionality related to the translation of Java code into JavaScript. They addressed issues with devirtualization, implemented and tested string and EnumSet emulation for JRE, and created functionality that allowed the generation of source maps and handling of different build environments. The user also worked on enhancing the compiler by implementing runtime exceptions, such as ArithmeticException, for various mathematical operations within the code.
