PROFILE
Jagath Weerasinghe
Worked on the hyperledger-labs/splice repository over four months, delivering eight features and resolving key bugs to enhance security, maintainability, and observability. Developed and refined APIs for external transaction hash traceability, implemented robust integration and performance testing, and introduced a Python-based metrics collector for Prometheus monitoring. Improved documentation and onboarding through technical writing and standardized git practices, while adding Grafana dashboards for performance visualization. Leveraged Scala, Java, and Python to build backend systems, optimize database management, and ensure reliable user management. The work focused on reducing operational risk, enabling external integrations, and supporting maintainable, testable workflows for the project.
