The Role

My first professional job in IT, between January 2007 and April 2008, within the regional government entity managing public healthcare across Vargas State (today La Guaira): regional hospitals and public outpatient clinics. The position encompassed two complementary halves that are inseparable in small administrations: building custom internal web applications and maintaining existing IT infrastructure.

That dual capacity—building software while operating infrastructure—remains central to my work today, nearly twenty years later, as I lead both software engineering and server systems for growing organizations.

Employee Credentialing and Badging System

The first production system I ever deployed. A web application written in PHP, JavaScript, and MySQL designed to issue official photo identification cards for employees across the entire state healthcare network.

Our team traveled directly to each medical facility: we located employee records in the central health database, retrieved employment status, medical title, and personal data, captured their photograph via connected webcam, and compiled the composite ID card ready for immediate output to a dedicated PVC plastic card printer.

The platform served approximately two thousand medical and administrative workers across four public hospitals (including the regional maternity hospital) and a dozen regional outpatient clinics.

Fast Payroll Inquiry Module

The Payroll department relied on an antiquated legacy mainframe system where querying worker records was painfully slow. Because the badging system had already established a reliable connection to the employee database, I leveraged that pipeline to develop a lightweight web-based lookup tool backed by a PostgreSQL replica of the employee dataset.

It did not replace the legacy payroll system: it coexisted alongside it, resolving its most frustrating bottleneck. It was my first experience solving technical challenges by building a modern perimeter around legacy systems rather than attempting a risky full replacement—an architectural approach I have employed many times since.

Systems, Networking, and Telephony

Beyond software development, I provided desktop support to healthcare staff (workstations, network printers, office software) and managed server infrastructure: alongside colleagues, I provisioned my first Debian production server and administered departmental Linux systems running Squid for proxy caching, iptables for firewall protection, and local DHCP/DNS services.

I also terminated network drops, structured cabling, and configured switches during an office renovation, and supported an Asterisk IP PBX telephone system, for which I completed specialized technical training.

Seventeen years later, I migrated corporate telephony for an enterprise group in Spain to a virtual cloud PBX. The fundamental problem remained identical; all that changed was where the PBX was hosted.
