PROFILE

Jeremy-then

Worked on backend and blockchain engineering for the rsksmart/rskj and rsksmart/powpeg-node repositories, focusing on peg-out reliability, fee estimation, and continuous integration improvements. Enhanced peg-out workflows by introducing SegWit-aware sizing, federation-aware logic, and robust error handling for batched simulations, using Java and Shell scripting. Improved CI/CD pipelines with GitHub Actions and integration testing, ensuring test relevance and reducing flaky results. Refactored fee estimation logic and introduced simulation-based methods controlled by activation rules, while maintaining code quality through targeted refactoring and SonarQube fixes. Defined constants for test reliability and supported larger federations, contributing to more stable and maintainable releases.
