Summary
🤩
Rockstar🎓
Top SchoolWyatt Alt is a Senior Software Engineer in San Francisco with 12 years building backend systems focused on databases, storage, and query engines. He has shipped petabyte-scale sensor data platforms at Cruise and worked on robotics and sensor data tooling at Foxglove, bringing practical experience with high-throughput, real-world telemetry. Early work on PuppetDB shows deep familiarity with centralized storage, messaging tuning, and operational configuration, and his open-source contributions include improving MCAP tooling for robotics and command-line clients in Go. Wyatt combines strong mathematical training from Reed College with hands-on DevOps and performance tuning skills, often touching both core database code and the deployment/configuration layer. Colleagues know him for solving tricky parsing and decompression edge cases and for pragmatic improvements that make large-scale data systems more reliable. He now applies that expertise to storage- and query-focused problems at LanceDB.

Contributions summary:Wyatt contributed code to the `foxglove/mcap` repository, which is a container file format for robotics and pub/sub applications. They implemented features related to handling empty MCAP chunks, improving the parsing of the format by addressing decompression errors. Additionally, the user added client code and a command-line tool for demonstrating the MCAP format in Go, which involved writing a new library and a tool for interacting with the file format. Furthermore, they added support for converting ROS2 db3 bagfiles into the MCAP format.
