Making the Internet a more usable and beautiful place since 2006.
My name is Miguel Ángel Sánchez Rubio and I’m a web designer and UI/UX developer based in Vinaròs, a lovely town on the Spanish shores of the Mediterranean.
Xtencil is my alias and my professional name. I've been a freelance designer since 2007, working with many design agencies and startup companies around the world.
During this time I've been involved in a wide range of projects, and I worked for all kinds of sectors: fashion, food, retail, e-commerce, sports, nongovernment... Among others.
In short, I'm a frontend developer who thinks that all design should never end in Figma or Sketch, but when it comes to life in HTML and CSS.
Associated agencies and tech partners
I enjoy working with good companies friends on exciting and challenging projects.

Working with Miguel has been an absolute pleasure. He's super professional, and his UX/UI work is top-notch. What really stood out was how involved he was and how much attention he paid to every detail. But above all, he totally got the strategic vision of the project and brought ideas that really made a difference. Honestly, a 10 out of 10!
Elena Andritchi, Marketing & CXM at bchange.ai
Miguel turned our initial idea into an even better version of what we had envisioned. Beyond that, he brings a level of insight and execution we haven’t found in any other design partner.
Nacho González, founder at Qointax.com
Miguel is an incredibly talented designer. He’s passionate about his craft and great at communicating his ideas while staying aligned with our needs. Our team keeps coming back to him for his outstanding, creative work.
Roberto Castro, product leader at Surikat.io
More than ten years and two redesigns later, I still work with Xtencil. My website has been nominated several times on Awwwards.com —not just for my art and videos, but for the excellent design work Miguel brings to the table.
Diego Latorre, artist and filmmaker
Thanks to his work and guidance, we ended up with a website exactly the way we envisioned it. We really appreciated his ability to listen and adapt to our ideas, creating a balanced, effective design.
Elisa Ruiz de Ojeda, CEO in FotoBB Reportajes
He quickly understood the brief, designed the pages with precision, and demonstrated excellent technical knowledge in both design and CSS layout throughout the project. The collaboration was smooth and professional from start to finish.
Nicolas Montigneaux, founder and CEO of Kidekom
Xtencil knows how to strike the perfect balance—creating designs that are visually appealing without being overdone, fully focused on functionality while maintaining originality. “Less is more” truly defines their style.
