Over eight months, contributed to the rsksmart/rskj and rsksmart/powpeg-node repositories by building and refining backend features focused on Bitcoin integration, blockchain fund handling, and CI/CD reliability. Developed and tested APIs for unsigned fund transaction hash management, enhanced federation storage, and improved peg-out fee estimation with SegWit and federation-aware logic. Strengthened test automation and code quality using Java, Shell scripting, and GitHub Actions, consolidating test suites and introducing reusable mocks and constants. Upgraded CI workflows to ensure integration tests remained current, reducing test drift and flakiness. These efforts improved release confidence, auditability, and the maintainability of critical blockchain infrastructure.
May 2026 for rsksmart/rskj focused on strengthening test coverage and reliability, driving business value through safer releases and robust fund-handling validation. The month delivered two major initiatives: (1) ReleaseTransactionBuilder test suite improvements, consolidating into a single nested structure with enhanced mocks, shared constants, and wallet integration to improve clarity and maintainability, and (2) SVP fund transaction tests expanded to validate input aggregation, multi-UTXO selection, dust edge cases, and correct fee accounting across SegWit and P2SH ERP paths. No production bugs were reported in this period, but these changes reduce regression risk, accelerate release readiness, and provide stronger guardrails for fund-related logic. The work also introduced reusable test helpers, mocks, and regtest-aware configurations to standardize testing across federation variants, delivering measurable reliability gains and deployment confidence.
