about

I'm a Full Stack Developer with a decade of experience in designing, developing, and maintaining web applications.
I have a strong background in software development, IT infrastructure, and network administration.

I specialize in backend and frontend technologies, including PHP, Laravel, JavaScript, SQL and VB6.
I am proficient in API integration, database management, and network administration, particularly with Mikrotik and Ubiquiti solutions.
Additionally, I have experience in Windows Server administration, virtualization, and remote access configurations.

I have extensive knowledge of invoicing systems in Uruguay and Portugal, having successfully led the certification process of our ERP with the tax authorities to ensure full regulatory compliance.
I also have expertise in generating SEPA XML files and integrating electronic invoicing standards.

Currently, I am expanding my skill set by exploring Flutter for cross-platform mobile application development (Android/iOS).
