REEN is an e-commerce platform where users can buy, sell, and manage dummy products. It’s inspired by one of the advanced projects from the Backend roadmap on Developer Roadmaps. I built it to strengthen my backend development skills with NestJS and to demonstrate my ability to develop sophisticated, modern full-stack applications with a robust backend architecture and an intuitive frontend.

Image Processing Service is a backend system similar to Cloudinary that allows users to upload images, apply transformations, and view or download the results. It’s one of the intermediate projects from the Backend roadmap on Developer Roadmaps. I built it to strengthen my backend development skills with NestJS and to demonstrate my ability to build high-performance, event-driven server-side applications with asynchronous processing, efficient caching, and real-time updates.

Real-time Leaderboard is a full-stack application that allows users to compete in various activities, track their scores, and view their rankings on a leaderboard. It’s one of the advanced projects from the Backend roadmap on Developer Roadmaps. I built it to strengthen my backend development skills with NestJS and to demonstrate my ability to build high-performance full-stack applications that efficiently manage and display user rankings in real time.

Movie Reservation System is a backend system that allows users to authenticate, browse movies, reserve seats for specific showtimes, and manage their reservations. It’s one of the advanced projects from the Backend roadmap on Developer Roadmaps. I built it to strengthen my backend development skills with NestJS and to demonstrate my ability to build robust server-side applications with complex business logic, strict data integrity rules, and role-based access controls.

Task Manager is a full-stack application built as a portfolio project, extending beyond The Odin Project’s Todo List project to demonstrate advanced web development skills. I created it using modern technologies like Next.js with TypeScript for full-stack development, PostgreSQL via Prisma ORM for persistent storage (replacing a previous localStorage implementation), and Clerk for secure authentication and user management. The project is deployed on Vercel for fast, seamless hosting with CI/CD integration.

Battleship is a web-based implementation of the classic Battleship game, built as part of The Odin Project curriculum to practice Test-Driven Development (TDD) and complex DOM manipulation. The project follows a TDD workflow using Jest (configured with Babel for ES6 module support), with comprehensive unit tests written to validate game logic and the computer opponent’s behavior.
