ABOUT ME

I’m Louis, a designer who works on both sides of a business: the brand customers see and the product teams use. My work runs from packaging and identity to UI/UX for websites, apps and internal ERP/CRM tools, and the design systems that hold them together.

In practice

I start with the business, not the visuals: who buys, who uses, what has to change. Then comes structured research, a clear information architecture, user flows, quick prototypes and a polished final UI, cutting anything that doesn’t earn its place. At CellphoneS I design tools used in daily operations; in my own products I test ideas directly in the market.

Since 2018

I design brands and products that run in real businesses

from packaging and identity to websites, apps and design systems

Every industry has its own users and constraints, so I start from the business before the pixels.

7+ years across retail, healthtech, edtech and SaaS, for local and international clients.

How I work

  1. Business first

    I find what has to change for the business, then design toward it.

  2. One brand, every door

    Pack, logo and screen should feel like the same company.

  3. Systems over one-offs

    Components and guidelines your team can keep using without me.

  4. Test early, say it straight

    Rough prototypes in front of real users, and honest feedback even when it’s not what you hoped.
