Oussema Jaouadi

Software & Site Reliability Engineer

I'm a Software and Reliability Engineer who loves creating systems that make a real impact. What excites me most isn't just deploying or maintaining them, but being part of the entire journey — shaping the architecture, making technical decisions, and seeing ideas come to life in production. Open to new challenges and relocation opportunities.

About Me

A dedicated Software & Site Reliability Engineer with a passion for building and maintaining robust, scalable systems

Computer Networks and Telecommunication Engineering student at INSAT, with a focused trajectory in Software & SRE. My 2 years of professional experience spans internships and freelance projects where I've delivered high-performance infrastructure solutions that prioritize reliability, scalability, and operational excellence.

My technical expertise encompasses the complete DevOps ecosystem — from containerization with Docker and orchestration with Kubernetes to infrastructure automation with Ansible and CI/CD implementation. This core competency is complemented by strong foundations in backend development and cybersecurity, enabling me to approach infrastructure challenges with a comprehensive perspective.

I thrive in environments that challenge conventional approaches and embrace innovation. My goal is to architect and maintain systems that not only meet the highest standards of reliability and performance, but also adapt elegantly to evolving business requirements and technological landscapes.
