I’m a software developer with strong full-stack experience, focused on building scalable, high-performance applications that deliver real business value.

As a Software Engineering Intern at Toyota Lanka Pvt Ltd, I helped develop internal and customer-facing systems, improving digital processes, data management, and overall system efficiency through close team collaboration.

On Autostream.lk, I built a microservices-based vehicle marketplace with multiple user roles, designed REST APIs for inventory/ads/valuation, implemented pricing logic using historical sales data (about a ~25% consistency improvement), and deployed with CI/CD to reduce deployment time from hours to under 10 minutes.

I also develop secure enterprise and data-driven platforms—such as an intranet with JWT authentication and role-based authorization, and an appraisal analytics system—plus AI/ML solutions like a migraine risk platform using Hugging Face models (about ~80% accuracy) and proactive alerts (about ~20% fewer severe episodes), reflecting my commitment to clean code, maintainability, and user-centric outcomes.
