PROFILE

David Percy

Over a two-month period, contributed to chalk-ai/chalk-go and chalk-ai/docs by building features that enhanced SQL data integration and improved documentation. Developed SQL-based input support for OnlineQueryBulkRequest, refactored data structures using Go and protobuf to align with evolving codebase requirements, and implemented compatibility fixes to ensure stable builds. In the documentation repository, delivered Chalk SQL Input functionality and restructured documentation for better accessibility, adding syntax highlighting and local viewing capabilities. Demonstrated skills in Go, SQL, and technical writing while focusing on maintainability, data querying, and developer experience, ultimately reducing integration friction and accelerating onboarding for future contributors.

November 2025: Delivered a critical enhancement to OnlineQueryBulkRequest in chalk-ai/chalk-go by adding SQL-based inputs (inputs_sql) and refactoring InputsFeather into a new Inputs structure to align with the updated codebase. Implemented a compatibility fix to resolve a compile-time issue caused by moving InputsFeather into a oneof, ensuring stable builds across configurations. The changes broaden data-source compatibility, enabling SQL-based data ingestion and improving maintainability for future refactors. Demonstrated Go development, refactoring, protobuf/oneof-style data modeling, and cross-team codebase alignment, delivering business value through reduced integration friction and lower risk of build-time failures.
