During November 2025, Daniel focused on enhancing correctness and test coverage for the positions feature in the rainbow-me/rainbow repository. He addressed a wallet balance discrepancy by excluding rETH from position calculations to prevent double-counting with stETH and wstETH, updating the token filtering logic and configuration. Using TypeScript and applying both front end and full stack development skills, Daniel expanded the unit and integration test suites to ensure accurate filtering across all three LSDs. This work improved the accuracy of wallet balances, reduced user confusion, and demonstrated thorough testing discipline, resulting in 166 passing tests and more reliable positions reporting.
