About Me

Frontend Developer crafting scalable web applications with a passion for motion and interaction.

Avatar

I'm a Frontend Developer with nearly 3 years of experience architecting scalable web applications using Hexagonal Architecture, TypeScript, and Next.js — writing code that's built to grow with the product, not just work for now. I have a strong interest in motion and interaction design, using tools like Motion to turn interfaces into something that feels alive, not just functional.
