Hi, I'm Mateo, Web Developer & UI/UX Designer
About
My Story
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.
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.
