About Me

I'm a Software Developer passionate about building mobile and web applications from scratch—designing and developing every detail is what I enjoy most.

I specialize in React Native (Expo) for mobile apps and Next.js for web projects. I also design my own UI/UX in Figma, ensuring each project is both functional and visually appealing. Most of my projects are team-based, where I enjoy collaborating and sharing ideas.
