During May 2025, Harsha focused on enhancing the CI/CD pipeline for the juspay/connector-service repository, targeting build reliability and maintainability. He introduced automated installation of the Protobuf compiler in GitHub Actions workflows using YAML, ensuring that Rust-based protobuf build steps executed consistently in continuous integration. Alongside this, Harsha standardized code style across the codebase, reorganizing imports and refining test macro formatting to support long-term maintainability. While no major bugs were addressed during this period, his backend development efforts centered on reinforcing coding standards and reducing CI gaps, ultimately enabling safer and faster deployments for the Rust and gRPC-powered service.
