Worked on the IntersectMBO/govtool repository to enhance the reliability of governance metrics by addressing a critical bug in stake pool operator (SPO) calculations. Focused on backend and database development using SQL and TypeScript, the work involved reverting previous hotfixes that had altered SPO stake and pool_votes logic. The approach simplified the data flow by removing the temporary LatestPoolStat table and recalculating total stake and vote percentages directly from pool_stat, ensuring accurate governance outcomes. By resolving duplicate entries and validating epoch data, the changes improved data integrity and reduced the risk of misreported SPO rewards and pool influence.
