Summary
🤩
Rockstar🎓
Top SchoolShehan Panditharatne is a founding engineer with 8 years of experience building scalable backend systems, full-stack platforms, and developer tools across startups and enterprise projects. Based in New York and trained at Columbia, he has driven performance improvements—doubling ML report generation throughput at Arklex and achieving 5x gains in analytics performance at WSO2—by combining code optimization, parallelism and load testing. A pragmatic generalist, he designs APIs and CI/CD workflows, mentors engineers, and has hands-on experience with Celery, RabbitMQ, Redis, Docker, Kubernetes and Azure. He is an active open-source contributor to stream-processing and language projects (notably Siddhi and Ballerina), where he’s fixed tricky aggregation and trigger bugs and extended language type support. That mix of research lab work (dialog systems), production engineering and documentation improvements makes him comfortable operating where requirements and boundaries are ambiguous.
