I’m a React Native developer passionate about creating seamless animations and writing elegant, type-safe code with TypeScript. I obsess over the details — every screen should flow beautifully, every interaction should feel intentional, and every line of code should make the product better.When I’m not building polished, production-ready apps, you’ll find me experimenting with new animation techniques, refining codebases to pixel-perfect standards, and sharing what I learn with the developer community. For me, great software isn’t just functional — it’s delightful.
