At PT. WiraAriandi Utama, I engineered a CRUD system for tracking operations with Laravel and Git, collaborating with a team of software programmers. I also developed the frontend for a mobile app supporting trail-running events, with interfaces for member registration and event sign-ups.
At Koding Next, I teach programming concepts to children aged 8–12 and develop presentation materials and 2D Roblox game-development modules. At Informatika - Universitas Mulawarman, I delivered classes in programming, data structures, web development, and artificial intelligence to more than 200 students.
