About Me

A dedicated 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 Site Reliability Engineering. 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.
