Ilyas Lutfi AbdatDigital Business student & developer

I'm Ilyas, a Digital Business student and multidisciplinary developer based in Bogor, Indonesia. I work at the intersection of software, hardware, and design—connecting the details to the bigger picture.

I've designed and shipped a production ERP and offline-first PWA covering finance, HR, POS, and operations, including an ESP32 biometric attendance system connected directly to payroll.

My studies in machine learning, business analytics, deep learning, and technology-driven project management help me bring both technical depth and business understanding to every build.
