Worked on backend development for the juspay/clairvoyance repository, focusing on improving the accuracy of date-based analytics queries. Addressed a bug in the calculation of relative date ranges by refining the logic to ensure that queries for the last X days now include today and cover exactly X days. This was achieved by adjusting the start date to Today minus (X-1) days, eliminating off-by-one errors and enhancing data reliability. Utilized Python to implement and test the fix, applying skills in prompt engineering and LLM integration to ensure robust and maintainable code. The work improved the reliability of analytics results.
