Description

Passionate web developer with over 20 years of experience, I develop Laravel/Symfony applications, PHP, and I am a DevOps specialist. I support my clients in the design, development, and optimization of their web projects, guaranteeing performance, scalability, and reliability.

Throughout my career, I have:

Led technical teams and complex projects, combining Laravel and other modern frameworks.
Deployed cloud-native applications, optimized with Docker, k8s, CI/CD, and advanced DevOps tools.
Worked on open-source projects that have strengthened my ability to code cleanly and collaborate effectively.

Whether you need a Laravel developer for a key project or a DevOps engineer to automate and secure your deployments, I am committed to delivering solutions tailored to your needs. My approach is pragmatic, results-oriented, and focused on fluid communication throughout the project.

Key Skills:

• PHP/Laravel Development (robust and scalable backend)

• Cloud Infrastructure (AWS, Docker, CI/CD)

• DevOps Automation to accelerate your processes

I would be delighted to discuss your projects and find solutions tailored to your needs! 🚀
