Design that’s clear, considered, and grounded in reality

Web Creativity is my independent studio, where I help founders and product teams make sense of complex digital products without noise, jargon, or process theatre. I believe good design comes from understanding the problem deeply, not just the interface. My work focuses on structure, usability, and collaboration, helping teams build products that are practical, thoughtful and designed to scale.

How I Support Teams

Here’s how I typically help teams move complex products forward.

I design clear, intuitive interfaces that help users move through complex products without friction. My focus is on structure first - layouts, hierarchy, and accessibility - with visuals that support the experience rather than distract from it. This usually includes user flows, wireframes, prototypes, and final hi-fi UI, depending on the stage of the product.

My Process

I work in a practical, collaborative way and adapt to the needs of the product and the team. Whether starting from scratch or improving something that already exists, I look at the product end-to-end, break down goals, identify gaps, and help teams make sense of complexity quickly. My approach is simple: understand the real problem, design around what actually matters, and work closely with engineers so ideas turn into things that ship. No bloated decks. No jargon. Just clear thinking, thoughtful design, and honest collaboration.

A Bit More About Me

Hi, I’m Carla a Senior Product Designer originally from Panama, now based in the UK. I have over a decade of experience working across startups, creative studios, and in-house teams, designing products that balance clarity, usability, and structure. I started out exploring both design and front-end development, which gave me a strong understanding of how products are built. While my focus today is product and interface design, that technical background still shapes how I think and work. Even in a digital world, I still start every project the same way: pen and paper first. I’m not here to chase trends. I’m here to make digital more human—balancing clean UI, solid UX, and design that thinks before it shouts. Outside of work, you’ll find me experimenting in the kitchen, learning new languages, or chasing after my daughter.
