Presentation

DesCode is a mobile learning platform designed to teach programming through interactive exercises and gamified experiences. Developed as part of my third-year Bachelor’s degree in Computer Science, this cross-platform application offers four distinct learning modes:

• Campaign (fundamental concepts)
• Languages (technology-specific tracks)
• Concepts (transversal programming principles)
• Learning Paths (curated curricula like “BUT Informatique”)

The project is composed of three main components: a React Native mobile application, a NextJS administration panel for content management, and a Rust REST API. The platform supports multiple exercise types, such as: multiple-choice quizzes, code completion, interactive terminal simulation for Shell, and more.

Key responsibilities

Backend Development

• Architected a type-safe REST API in Rust using Axum and Tokio
• Implemented automated TypeScript generation using ts-rs to synchronize types between Rust backend and TypeScript frontends, eliminating API contract drift
• Designed PostgreSQL schema with SeaORM migrations
• Built a custom integration testing framework with Docker-isolated environments

DevOps & Infrastructure

• Deployed containerized architecture on OVH Cloud VPS using Docker Compose and Traefik reverse proxy
• Built CI/CD pipeline with GitHub Actions featuring: automated testing, Clippy/ESLint checks, security dependency auditing, Docker image optimization, and automatic NPM package publishing to private registry

Interactive Features

• Created sandboxed code execution environment using Piston API for safe runtime validation of user-submitted code
• Built WebSocket-based Shell simulator providing real-time terminal interaction for command-line learning exercises
• Implemented AI-powered translation using OpenRouter (Gemini Flash) to automatically translate educational content in the admin panel
