I’m Kavinda Rathnayake, a Full-Stack Developer focused on building high-performance, scalable applications across web, mobile, and desktop platforms. I engineer with a "performance-first" mindset, leveraging TypeScript, Java, and Rust to architect robust systems from the ground up.
I specialize in TanStack Start, Next.js, and React Native for client-side architectures, paired with high-throughput backend services using Node.js/Express.js and Spring Boot/Java, and utility tooling using Rust. I love solving complex architectural problems like multi-tenant isolation, real-time cache synchronization, and event-driven microservices.

⭐ Fun Fact: I love the challenge of picking the right tool for the job, whether it’s the rapid iteration speed of TypeScript or the strict memory safety and raw performance of Rust.
