## About

```text
As a freelance Software Engineer & DevOps specialist, I engineered a Next.js and TypeScript showcase application for Kitchen Express. It scored 98+ on Google Lighthouse, and the work included optimizing asset delivery and server-side caching.

In my freelance full-stack work, I developed an e-commerce platform with React.js, Node.js, and MongoDB, and configured Linux staging and production environments with continuous deployment. At Elitecom, I developed a real estate management platform and managed Jenkins CI/CD releases.

At IPACT Consult, I expanded enterprise software features using the MERN stack and incorporated SonarQube checks into Jenkins pipelines. At ESPRIT, I led a four-developer team building a collaborative document management platform.

I also spearheaded Scam Radar, an AI-powered fraud awareness platform that won 2nd Place in Tunisia at the GOMYCODE x NVIDIA Hackathon. I designed its message scanner and built trilingual interfaces in English, French, and Arabic.
