About Santiago

I am an illustrator and UI/UX designer with over 15 years of experience transforming education through design. I specialize in creating interactive and gamified digital experiences, with a strong focus on usability and accessibility for the EdTech sector.

My passion is bringing educational content to life through interface design, character creation, scenarios, and visual narratives that generate real user engagement. I have worked on the entire product lifecycle: from conceptualization and prototyping to animations and design systems, for major international publishers (Edelvives, Oxford, Pearson, Santillana) with well-received products in the market.

What I can contribute to your project:
- Interface Design (UI/UX) for Education: Creation of intuitive apps and platforms that guide learning frictionlessly.

- Gamification and Narrative: Experience in developing visual universes and reward systems, such as the integral design and characters for the Ta-tum platform (Edelvives).

- Editorial and Digital Illustration: Careful aesthetics adapted to different age ranges, always maintaining didactic coherence.

- 360º Product Vision: I understand the needs of both the publisher/developer and the end-user (teachers and students).

My methodology:
I work remotely for teams anywhere in the world, integrating into agile workflows. I also have a team of developers for projects that require it.
