Worked on opsmill/infrahub to enhance developer experience and improve the reliability of time-based queries in backend systems. Focused on standardizing the local backend build and testing workflow, introducing consistent commands and updating documentation to streamline onboarding and reduce environment drift. Refactored branch query helpers to enforce Timestamp inputs, ensuring more reliable and accurate time-range operations. Updated unit tests and aligned them with API changes to minimize flaky failures and improve data correctness. Utilized Python for backend development, API design, and comprehensive documentation, resulting in a more consistent development environment and improved integrity of time-handling logic across the project.
