Ramadhani Nur Sarjito
Full-Stack Developer
I design and build scalable, maintainable, and secure full-stack applications.
Hello! I’m Rama, and my journey in coding started in 2019 when I was inspired by my older brother. However, it was the encouragement from lecturers on campus in 2021 that made me really focus and be consistent in learning. Since then, I have become increasingly interested in exploring various aspects of the programming world.
I started by learning Python, but soon realized that I was more interested in user interfaces. This led me to switch to frontend web development. Mastering HTML, CSS, and JavaScript became my priority, and I started exploring different technologies that support the creation of engaging and interactive web applications.
Currently, I`m developing into fullstack JavaScript and TypeScript, focusing on frontend and backend development as a whole. I love learning new things every day and am always open to feedback to keep growing and improving my skills.
Managing transport service products — such as membership cards and vouchers — isn't just about sales. Every step from creation to customer use must be controlled and traceable. Previously, processes like card generation, distribution, and transaction validation were handled manually, making them slow, error-prone, and difficult to monitor. Two core products also needed to be managed within the same ecosystem: Frequent Whoosh Card (FWC) as a membership program for regular commuters, and Vouchers as a prepaid travel product. To address this, I helped build an integrated platform that manages both products end-to-end — from product creation and serial number generation, to stock distribution across locations, field transaction recording, and real-time validation and redemption.
