CODE (Competition of Developers) is an annual national-scale technology event organized by Amikom Computer Club. The 2024 edition, themed "Mastering the Tech Landscape," combined competitive programming and software development competitions with a National Seminar. As part of the Secretariat Division, I held a hybrid role. Technically, I designed and developed the web components for the National Seminar page using a lightweight stack (HTML, Tailwind CSS, and Alpine.js) to ensure high performance and responsiveness. Operationally, I acted as a key liaison for participants, managing inquiries and handling the on-site digital registration process to ensure a seamless experience for hundreds of attendees.
