Hi, I'm Mohamed Bettache
|
I’m a Full-Stack Developer and product builder who enjoys turning ideas into real, production-ready products. I build across the stack with React, Next.js, FastAPI, NestJS, and PostgreSQL, from polished interfaces and dashboards to APIs, authentication, databases, and deployment. I’m a co-founder of DzStore and Fibble, and I’ve built products of my own, including a full-stack Expenses Tracker. I focus on building software that solves real problems, from idea and architecture to a polished, production-ready product.
Full-Stack Developer & Problem Solver
I build production platforms that real users and paying clients depend on, end to end.
What I do
I build and ship full-stack web products end to end, from database architecture and API design to responsive interfaces, authentication, and production deployment. My work spans React, Next.js, FastAPI, Express, NestJS, PostgreSQL, and Prisma, with a focus on building applications that are reliable, secure, and ready for real users. I also enjoy integrating AI into products, from AI-powered applications to analytics and intelligent workflows.
Beyond client andFull-Stack Developering work, I’m a co-founder of DzStore and Fibble, where I’ve helped turn ideas into products used by real people. I’ve also built my own SaaS products, including an Expenses Tracker, as well as backend systems such as authentication APIs and subscription management services with automated workflows and email notifications.
I care about more than writing code. I enjoy taking ownership of a product, solving problems across the stack, and turning an idea into something useful, maintainable, and production-ready.

- Real-time multiplayer games for 2–8 players
- Bluff-based trivia with player-generated answers
- Custom question packs and media-based questions

- JWT access and refresh token authentication
- Secure refresh token rotation
- Role-based access control and admin APIs
- Email verification and password reset
- Audit logging with IP and user-agent tracking
- Rate limiting and brute-force protection

Real-Time Chat Backend — FastAPI
Backend Developer
Built a real-time chat backend using FastAPI with WebSocket communication, conversation management, message persistence, authentication, and a PostgreSQL database.
