Hello, my name is Agung Gumilang and I have over 4+ years of experience as a Full Stack Web Developer for a hosting provider company. My day-to-day work involves developing and maintaining solutions around REST API and WHMCS platform, where I build custom modules and integrate third-party services to streamline client management and billing operations. On the backend, I work with PHP (Laravel, CodeIgniter, and WHMCS platform) to deliver robust and safe REST API, while on the frontend I leverage JavaScript, Bootstrap, and Vue.JS to deliver not so fancy but clean, user-friendly interfaces.
