Developed a telemetry enhancement for the microsoft/AL-Go repository, focusing on enabling custom time range filtering within the Telemetry Dashboard. This work involved updating backend Kusto queries to utilize the between operator for timestamp fields, allowing users to select precise data windows and overcoming previous limitations in time-range selection. By leveraging backend development and data querying skills, the solution streamlined trace data analysis and reduced the need for manual data wrangling. All changes were implemented using JSON and Kusto Query Language, with clear commit traceability and documentation to support ongoing telemetry improvements and facilitate future enhancements within the repository.
