I’m Kavinda Rathnayake, a Full-Stack Developer focused on building high-performance applications across all platforms. Whether it’s a scalable web app, a native mobile experience, a lightweight desktop tool, or secure on-chain logic, I build with a "performance-first" mindset.
I specialize in TypeScript and Rust, leveraging Next.js for the web, React Native for mobile, and Tauri for desktop. On the backend, I switch between Node.js/Bun for speed of development and Rust (Axum) for high-throughput, mission-critical systems.
My background in Web3 allows me to integrate decentralized components seamlessly, utilizing Solidity and the Foundry framework to build secure smart contracts and robust DeFi infrastructure.
