PROFILE

Heshan Sudarshana

Over a three-month period, this developer focused on backend and API development across the wso2-synapse and wso2/product-apim repositories, using Java and JavaScript. They stabilized connection lifecycle handling by simplifying shutdown logic, reducing fault-triggered closures, and clarifying error management to improve maintainability under adverse network conditions. Their work on dependency management in wso2/apim-apps ensured deterministic builds by pinning npm versions, reducing CI variability. Additionally, they enhanced security by implementing mediator access controls for XML parsing and switching to allowlist-based script access, while also optimizing test performance by replacing Thread.sleep with a busy-wait loop for faster feedback during testing.
