Worked on the 0xPolygon/heimdall-v2 repository, focusing on enhancing the reliability and coverage of ABCI protocol interactions and side-transaction flows. Delivered a comprehensive suite of tests for ABCI handlers such as PrepareProposal, ExtendVote, and VerifyVoteExtension, as well as for side-transaction modules like PreBlocker and Bor/Clerk/TopUp. Addressed a runtime bug in the ExtendVoteHandler contract caller initialization, improving cross-module stability. Employed Go and the Cosmos SDK, applying test-driven development and code refactoring to catch edge cases early. These efforts strengthened deployment safety, accelerated release readiness, and improved the maintainability of distributed blockchain backend systems.
