A web-based stock opname system developed with Angular and Express.js for the BNSP Software Programming Certification, featuring a responsive dashboard, multi-criteria search, dynamic KPI cards, and an interactive staff help guide.
Hey there! I’m PUTRA, I spend most of my days building apps (mostly web), exploring about new tech (sometimes), and fighting an endless battle with mysterious errors.
I love figuring out how things work, creating stuff that’s actually useful (or at least looks cool), and learning as fast as I can. Still growing, still exploring, still breaking things before fixing them again — but that’s all part of the fun, right? :D
Open to any opportunity that helps me level up, learn faster, and face new challenges.
If it sounds exciting, count me in — let’s build something cool together :D
