Harun, a 12-year-old solo developer, has created KODA, an AI coding mentor developed on an Android phone. He is launching the "KODA CODE JAM" challenge to encourage beginners and demonstrate the power of AI assistance in building projects. The mission is to create a single-page, useful website for a niche market, offering examples like dog walkers, gamers, baristas, and students. Participants must use KODA for at least 50% of their code and showcase their prompts. Submissions require a live link or GitHub repository. The grand prize includes permanent Champion Status in KODA with exclusive perks, a featured interview on Harun's Dev.to blog, and social media shoutouts. Runner-ups will receive a special "Code Jam Participant" badge on their KODA profile. The challenge begins tomorrow, August 27, 2026, with a deadline of September 2, 2026. Winners will be announced on September 4, 2026. To join, users need to sign up for KODA, start interacting with the AI, build their site, and submit their link in the comments. Harun emphasizes that coding is about problem-solving, and KODA aims to accelerate this process.
