Fullstack Developer — Frontend Specialist

John Maders

About Me

Hi! I'm João — but you can call me John — a fullstack web developer with 5+ years of experience building and maintaining scalable WordPress sites, e-commerce platforms, and internal tools.

I specialize in pixel-perfect frontend implementation with HTML5, CSS3/SASS, modern JavaScript, and React — transforming designer mockups into production-ready code. On the backend, I'm comfortable extending WordPress through custom PHP, hooks, filters, custom post types, and the WP REST API.

I'm production-safe with Git workflows, SSH deployments, and Linux-based server environments. Not a page-builder-dependent developer — I work directly in code to deliver quality solutions.

Outside of work, you'll find me spending quality time with my cats, going for runs, and enjoying a good cup of coffee ☕. I believe balance between coding and personal wellness is key to staying creative and motivated.
