AI/ML & Data Governance Consultant

I had the opportunity to work closely with Pramitha on the development of our SaaS-Based NS-3 for Scalable and Reproducible IMT-2030 Evaluations platform, where he made a significant contribution to the software architecture and distributed system design. Jayasooriya played a key role in designing the core application architecture, particularly around SaaS enablement, distributed execution workflows, and backend service integration. His strength lies in understanding how systems should be structured for scalability, maintainability, and long-term product evolution... What stands out about Pramitha is his systems-level perspective. He understands how distributed components interact, how services should scale, and how architectural decisions impact long-term sustainability... I highly recommend Pramitha Jayasooriya to international product teams and fast-growing startups looking for a thoughtful, technically capable, and future-oriented software engineer.

Pramitha is a diligent, hardworking person. I worked with him on a key project while he was interning at WSO2. He handled the whole project by himself, delivered on time and was open to suggestions and feedback. He did a great job! I’m sure he will do great in a long career he has in front of him. All the best, Pramitha!
