Will Gilliam contributed to several open-source projects, building robust backend and frontend features across AnswerDotAI/fasthtml, AnswerDotAI/MonsterUI, and BerriAI/litellm. He enhanced APIRouter in fasthtml by implementing route prefixing, multi-file organization, and improved error handling using Python and object-oriented design. On MonsterUI, he developed a reusable CalendarInput component in JavaScript and HTML, standardizing date entry and validation. For BerriAI/litellm, he improved Braintrust integration metadata and documentation to support accurate cost estimation. His work also included observability improvements and tracing enhancements in braintrustdata/braintrust-sdk, demonstrating depth in async programming, API integration, and test-driven development across diverse codebases.

July 2025: Delivered observability and onboarding improvements across two Braintrust repos, with concrete traceability, robust tests, and developer-facing assets. Strengthened reliability of tracing, enhanced sample content for developers, and fixed key quality issues to accelerate issue resolution and adoption.
