About Santi

With over 10 years of experience in implementing digital projects – from corporate websites and SaaS web applications to e-commerce platforms – I bring in-depth expertise and a passion for high-quality user experiences.

My focus is on developing well-thought-out and user-friendly designs that meet both user requirements and budget and resource constraints.

I always pay attention to details and ensure that design systems and CI guidelines are consistently adhered to, while simultaneously incorporating creative approaches for further development.

Thanks to my long-standing collaboration with developers and my experience in the Scrum framework, I am able to drive design processes in a structured, solution-oriented, and efficient manner.

My structured and self-reliant working method, combined with a high level of problem-solving competence, makes me a reliable partner for projects of any size.

I look forward to supporting your company with my expertise in UI/UX design.
