Open to Java backend roles

Building reliable backends with Java and Spring Boot.

I'm a Software Developer with a B.Sc. in Computer Science, and I build REST APIs, databases and server-side logic for business applications. I recently built Vekso, a multi-vendor marketplace, as a freelance project. As a Software Developer at ThulirSoft, I build hiring, task-management, e-commerce and assessment platforms with Laravel, React and Flutter. I've also solved 360+ problems on LeetCode — giving me a strong foundation in data structures and algorithms.

About me

I build web and mobile applications end to end. At ThulirSoft I've worked on 15+ client and internal projects, and I built several of them myself, from database design to deployed APIs and front ends. I'm now looking for Java backend developer roles where I can design reliable, scalable services with Spring Boot.
