Student Developer & Tech Problem Solver

Hello! I'm Ezikiel Pesquiza, a dedicated 2nd-year Information Technology student based in Mandaluyong, Philippines. My drive in computing is centered on building practical software solutions that bridge scalable system architecture with responsive, accessible user experiences.

Through hands-on laboratory machine problems and term coursework, I have developed strong competencies in Java Object-Oriented Programming (OOP), Relational Database Modeling (SQL), Modern Web Technologies, and High-Fidelity UI/UX Prototyping. Every challenge is an opportunity to write cleaner code, solve complex problems, and engineer dependable systems.
