What I'm looking for

I am looking for a dynamic work environment that fosters innovation and collaboration, where I can apply my skills in DevOps and automation while contributing to impactful projects.

I am a Modeling and Infrastructure Engineer with a strong foundation in DevOps practices and automation technologies. Graduating from the National School of Computer Science, I have honed my skills in various programming languages and cloud platforms, enabling me to tackle complex challenges in infrastructure management.

Currently, I work at Kopileft, where I have successfully developed optimized Puppet classes for environment management, designed robust PostgreSQL backup solutions, and implemented advanced scripts for anomaly detection. My experience also includes significant contributions to migrating PHP websites to on-premise infrastructures, ensuring secure network communications through VPN and firewall administration.

Throughout my internships, I have gained hands-on experience in setting up monitoring and logging solutions for Kubernetes applications, utilizing tools like Grafana and Prometheus. I am passionate about leveraging my skills to enhance system performance and reliability, and I am eager to contribute to innovative projects in the DevOps field.
