PROFILE
Arya Lanjewar
Arya Lanjewar contributed to the 0xPolygon/heimdall-v2 repository by building and enhancing comprehensive testing frameworks for ABCI protocol flows and side-transaction logic. Arya expanded test coverage for critical handlers such as PrepareProposal, ExtendVote, and VerifyVoteExtension, and implemented a milestone propositions testing suite to validate generation and retrieval logic. Using Go and the Cosmos SDK, Arya focused on test-driven development, regression testing, and code refactoring to improve reliability and catch edge cases early. This work stabilized cross-module interactions, reduced production risk, and enabled faster iteration cycles, demonstrating depth in backend and distributed systems engineering within blockchain infrastructure.
