About

Professional summary

I am a fifth-year IT Engineering student specializing in full-stack, mobile, and web development. I build practical software products across mobile interfaces, backend APIs, databases, and deployment workflows.

I have hands-on experience delivering Flutter applications, including IoT control and monitoring solutions, transport services, and real-time booking platforms. I enjoy turning product requirements into reliable user experiences and scalable technical architectures.

My backend experience includes Node.js, TypeScript, Spring Boot, NestJS, REST APIs, WebSockets, and relational and NoSQL databases. I am comfortable designing service layers, data models, real-time communication features, and booking workflows.

I also work with embedded systems and edge AI. I have integrated Arduino and ESP32 sensor nodes with MQTT services, and I have trained and deployed YOLO-based computer-vision models for offline inference on edge hardware.

I bring DevOps and security awareness to my work through Docker, CI/CD, Git-based collaboration, Linux, OpenSSL, and monitoring tools. I am seeking a consulting-oriented full-stack or mobile development role where I can rapidly contribute across the product delivery lifecycle.

I am based in Nabeul, Tunisia, and communicate professionally in Arabic, French, and English. I am motivated by challenging projects that combine software engineering, mobile development, IoT, and intelligent systems.
