Albert — Senior IT Specialist & Backend Systems Engineer

I am an IT Specialist with 12+ years of experience designing and delivering enterprise web applications, centralized data systems, and internal digital platforms. My focus is PHP backend development, database architecture, Linux infrastructure, and system integration.

Most of my work involves multi-branch operational systems: consolidating data spread across several databases, automating financial workflows, and bridging legacy systems with modern technology without disrupting live operations.

Several systems I built improved operational efficiency by up to 65% and reduced manual workflows by over 75%.

I focus on building secure, maintainable systems with clear technical foundations.

Backend Development

REST APIs, authentication, service integrations, and reliable background processing.

Database & System Design

Relational data modeling, query optimization, and foundations that stay maintainable.

Business Applications

Attendance, warranty, scheduling, reporting, and internal operational tools.
