Rockstar🎓
Top SchoolSanoj Punchihewa is an Associate Technical Lead and software engineer with nine years of experience, currently contributing to WSO2’s cloud-native integration stack from Sri Lanka. With a Computer Engineering degree from the University of Peradeniya and a long-running side venture building Android apps, he blends product-minded engineering with hands-on backend and API development. His open-source work on WSO2 projects (carbon-mediation, product-micro-integrator, and wso2-synapse) shows practical expertise in integration runtime APIs, inbound endpoint behaviors, and adding OAuth password-grant support to HTTP endpoints. He’s particularly skilled at mapping query parameters to message contexts, refactoring for testability, and designing management APIs for synapse artifacts and log controls. Quietly entrepreneurial, he maintains an independent mobile-app studio while driving integration features at an enterprise middleware vendor.
