Kelpin Hartanto Backend Engineer & Mobile Enthusiast

Hey! I'm a software engineer who loves building things that are fast, reliable, and efficient. Most of my time goes into backend development especially with Golang because it's clean, powerful, and perfect for high-performance systems. I also use PHP (Laravel) when I need something flexible and quick to develop, especially for dashboards, admin panels, or full-stack web apps. For the UI side, I enjoy working with Flutter mainly because it lets me ship beautiful, consistent apps for iOS and Android without dealing with two separate codebases. Honestly, nothing beats the satisfaction of seeing a solid backend running smoothly behind a responsive, well-crafted product. In short: I love building systems that feel smooth for users and satisfying for developers.
