About

I’m Selennur — you can call me Selen — a Full-Stack Developer whose journey into technology began during my master’s studies, where I was first introduced to coding. What started as academic curiosity gradually developed into a clear professional direction, leading me to pursue software development as a career. Since then, I’ve focused on building practical skills and applying them through real-world projects that strengthen both my technical understanding and problem-solving approach.

Full-stack Developer

Motivated by curiosity and continuous growth, I approach development as a balance between logic and creativity — structuring solutions while shaping how users experience them. I enjoy tackling challenges, refining ideas into practical outcomes, and crafting interfaces that feel intuitive and engaging. My goal is to build applications that are not only functional, but meaningful, accessible, and thoughtfully designed.

I value collaboration, continuous learning, and delivering thoughtful, user-focused solutions to real-world challenges.
