Charl Concepcion

Hello! I'm Charl Concepcion. A full-stack web developer based in the Philippines. I'm certified on freeCodeCamp as a full-stack software engineer and I create web applications with design and performance in mind.

What started as a hobby in 2022 has become AcceleratedIT — serving businesses, LLCs, and government entities globally. The name CTX comes from the canvas context variable — the rendering surface where everything becomes real.
