Freelance Slim Khardani

Slim — Computer Engineering Student & Full-Stack Developer

I’m a Computer Engineering student (DNI) at ISSAT Sousse with a solid 7-year background as an IT technician, giving me a rare mix of hands-on hardware experience and modern software development skills.

On the development side, I work with NestJS microservices, REST APIs, JWT/bcrypt authentication, file handling, and Docker-based architectures. I’ve built and maintained production-grade backend services and have practical experience with tools like Git,and API proxying.

I’m also active in AI automation, building intelligent workflows using n8n, LLM APIs (Gemini, Groq), and no-code integrations like Google Sheets, Gmail, and Notion — helping businesses automate repetitive tasks and save time.

My broader skill set includes:

• Backend: NestJS, Node.js, REST APIs, microservices, JWT auth
• AI Automation: n8n, LLM integration, workflow design
• Systems & Networking: Linux (Ubuntu), Cisco networking, real-time systems
• Blockchain: Hedera Hashgraph (HashGov project)
• Tools: Docker, Git, Postman, Packet Tracer

I’m detail-oriented, fast to learn, and comfortable working in both French and English. Whether you need a backend service built from scratch, a smart automation workflow, or IT support — I deliver practical, reliable results.
