Hello, I’m

Tiberio Calderón

Software Engineer with a Quality-First Mindset

I’ve spent over 9 years in QA, making sure products are reliable and user-friendly. Today, I combine that experience with my passion for web development to build modern, accessible, and high-quality digital experiences.

Let's talk

My Intro

About Me

I’m a Software Engineer who loves building great user experiences and making sure things actually work. For more than 9 years, I have worked in QA, testing everything from web platforms and mobile apps to complex payment systems. Along the way, I developed a strong eye for detail, accessibility, and user-centered design.

More recently, I completed a postgraduate program in Full-Stack Software Development in Canada, where I sharpened my coding skills and deepened my interest in building modern web applications.

Today, I’m excited about roles where I can mix what I do best — ensuring quality — with my growing experience in development, whether that’s in QA, automation, or front-end engineering.
