Summary
👤
Senior🎓
Top SchoolHasitha Abeykoon is a Senior Technical Lead with 12 years of experience designing and delivering enterprise integration, message-broker systems, APIs and backend microservices, primarily at WSO2. He has led large engineering teams and customer migrations—most notably a Mule-to-WSO2 migration for a US insurer that produced 120+ production integration flows under tight deadlines. A hands-on contributor to open-source integration tooling, he improved concurrency and caching behavior in the widely used Apache Synapse project and added tests to raise code coverage. Hasitha combines product-focused engineering (building connectors, operators, and tooling for WSO2 Micro Integrator and Choreo) with on-site customer engagements and training, bridging delivery and adoption. He is comfortable both managing teams and diving into low-level concurrency fixes, and has a track record of standardizing connector development and improving runtime performance. Based in Sri Lanka with a BSc in Computer Engineering from University of Moratuwa, he brings a pragmatic blend of systems thinking, customer empathy, and deep integration expertise.
