ERP & Web Developer | Telegram Bot | Khmer Font Designer

Hello! I'm Kong Rotana, an experienced ERP Developer specializing in SAP Business One (SAP B1) customization and add-on development. I build efficient business solutions by integrating SAP B1 with modern technologies to streamline operations and improve workflows.

Beyond ERP, I also work in full-stack web development using MVC architecture, and I've been developing Telegram bots for over six months—automating tasks and creating interactive tools for users. With a strong foundation in graphic design (2+ years) and typography, I'm also the creator of the Khmer typeface Chhuk Krapom Font, designed to support beautiful and legible Khmer script across digital platforms.
