Java back-end developer building scalable Spring Boot APIs and MongoDB solutions.
IndonesiaWhat I'm looking for
I’m a back-end developer focused on building reliable services with Java and Spring Boot. I enjoy turning requirements into clean APIs that are practical to maintain and easy to extend.
Since December 2021, I’ve worked as a Back End Developer at Closepay, strengthening my backend depth and system thinking. Before that, I gained broader exposure as a Full Stack Engineer from May 2018 to December 2018.
My technical foundation includes MongoDB for data persistence and Java for core application logic, supported by my education at Institut Teknologi Sepuluh Nopember. I bring a backend-first mindset with the ability to collaborate across the full stack when needed.
