Julian Cantera

WordPress & Front-End Developer

I build accessible, pixel-perfect digital experiences for the web.

About

In a different era, I thrived as an outgoing, cheerful, and passionate individual. For over more than seven years, I immersed myself in the role of a tourist guide in London, narrating the city’s rich history to happy visitors. However, the constant human interaction eventually took its toll.

In 2018, I made the tough decision to change careers, driven by my enduring passion for computers that has been with me since the dawn of the web. I’ve always been a bit of a nerd, eagerly exploring the intricacies of technology. Making the shift from people to computers has transformed me into the opposite of what I once was. Yet, in this digital realm, machines don’t judge, do they ChatGPT?

Started as a software tester – dull, monotonous. However, I gained insights into the industry dynamics: project managers, clients, Agile, Scrum, Front-End, Back-End, OOP, responsiveness and so on. Testing wasn’t my forte. Former colleagues suggested working on their WordPress site, and that’s when the spark of love for development ignited. The pandemic provided ample time to study, practice, break websites, fix them, and break them again.

Since then, I’ve worked both independently and in teams, continuously learning, staying updated, all the while hoping AI won’t snatch my job. Curious for more? Please, Keep scrolling down.
