During May 2026, contributed to the lichess-org/berserk repository by delivering a major API enhancement focused on export methods. Developed and integrated an accuracy parameter into multiple Games export endpoints, allowing developers to control the precision of JSON data exports. This addition improved data reliability and performance for data-driven applications, enabling more efficient payload management and flexible integration. The work involved careful API parameter design, Python-based implementation, and alignment with existing endpoint standards to ensure seamless adoption. Emphasizing API development and software engineering best practices, the changes reinforced the repository’s stability and prepared the groundwork for future documentation and testing.
