About Mehdi

I am a Full Stack and Mobile developer, specializing in creating secure and performant applications. With expertise in Python, Java, JavaScript, and Flutter, I design custom web and mobile solutions to meet the specific needs of my clients.

My approach is distinguished by the systematic integration of best security practices. Whether you need a high-performance mobile application on iOS and Android with Flutter or a robust and scalable web application, I will guide you throughout the process, from design to production. I master technologies like Spring Boot, FastAPI, Angular, React.js and work with DevOps tools (Docker, Kubernetes, GitLab CI/CD) for smooth and scalable project management.

Security is at the heart of my concerns. Thanks to my expertise in DevSecOps, I ensure that each application is protected against common attacks like XSS, SQLi, and CSRF, while guaranteeing safe and efficient development practices. I integrate security tests from the design phase and ensure continuous performance optimization through CI/CD processes.

I work in an agile manner (Scrum) to ensure project flexibility and adaptability, offering close collaboration with business and technical teams. My goal is to create applications that not only meet your needs but also exceed your expectations in terms of security, performance, and scalability.

The projects I manage include the development of mobile applications, the creation of secure APIs, and the optimization of the performance and security of existing applications. Do not hesitate to contact me to discuss your project and see how I can help you achieve your goals.
