01 — Speed is a feature
A fast site converts better and ranks higher. I budget every page under two seconds on a mid-range phone, then prove it with real measurements.

My Story
Developer, designer and coffee enthusiast — building websites that feel effortless since 2016.
Hello! I'm Mateo, a web developer and designer who likes small, fast sites that are easy to look after. I started in front-end work and gradually took on back-end and design, so I can carry a project from first sketch to live launch.
I follow new tooling closely but only adopt it when it makes a site quicker, simpler or cheaper to run for the client.
Semicolon Studio is my one-person practice for doing that work properly: no bloated themes, no page builders held together with plugins, no 9-second load times. Every project is hand-built in modern JavaScript, designed around your customer and measured against outcomes — enquiries, sales and signups, not just compliments.
Away from the screen you will usually find me on a long run or testing a new espresso recipe. Tell me about your next project and let's make it real.

How I Work
Three rules behind every build
02 — Design serves the reader
Typography, spacing and hierarchy do the persuading. Decoration never gets in the way of someone trying to contact you or buy from you.
03 — You own everything
Clean code, honest docs and a handoff call. Update text yourself, extend pages later, or hand the whole thing to another developer.
