About Christian

Do you need to develop, improve, or recover a PHP application without wasting time understanding messy code? I can help you turn your requirements into a stable, secure, and scalable backend.

I am a backend developer specializing in PHP and Symfony, with over 15 years of experience in software development, databases, and Linux server administration. I primarily work on:

• Development of REST APIs and backend applications with PHP and Symfony.
• Administrative systems, management panels, and process automation.
• Integration of web and mobile applications with APIs.
• User authentication using JWT and permission management.
• Modeling and optimization of MySQL and MariaDB databases.
• Maintenance, bug fixing, and expansion of existing systems.
• Deployments, migrations, and configuration of Linux servers and VPS.

Among my projects are RepaOnTrack, a backend to manage the repair cycle of components and equipment, and Atila Money, an application for income and expense control developed with Symfony, Vue.js, REST API, JWT, and MySQL/MariaDB.

I am characterized by carefully analyzing each requirement, clearly communicating progress, and proposing realistic solutions. I can participate from the design of the database and API to the implementation, documentation, deployment, and maintenance of the system.
