About
Detail-oriented junior software developer with a support background and a passion for building reliable, practical solutions.
I’m a dedicated software developer with hands-on experience designing and building Java desktop apps, Android apps,
and modern web applications. I enjoy turning requirements into clean, maintainable code and I’ve worked with tools
like Spring Boot, React, MySQL, JPA, and REST APIs.
My previous roles in IT support and application support taught me how to troubleshoot under pressure, communicate
clearly with non-technical users, and keep systems running smoothly—skills I now apply as a developer.
