12-Year-Old Developer Builds AI Coding Mentor Entirely on a $150 Android Phone

A 12-year-old developer has successfully launched KODA, an AI-powered coding mentor designed to assist beginners with debugging and project development. Remarkably, the entire project was built using a $150 POCO C55 Android smartphone, challenging the notion that high-end hardware is a prerequisite for software development. The architecture utilizes a lightweight, mobile-first approach, relying on a vanilla HTML, CSS, and JavaScript frontend. For the backend, the developer integrated Supabase for authentication and database management, while implementing a robust fallback chain for AI requests via APIs like Groq and OpenRouter to ensure reliability. This project serves as a testament to the idea that technical constraints can foster creativity and accessibility in software engineering. The developer aims to lower the barrier to entry for coding, proving that significant tools can be created with minimal resources.
