Design and build are not separate disciplines here. Form and function is one single decision.

Competitive and market analysis, user research and brand positioning, before a single screen gets designed.

About

Building what I design taught me to think beyond the screen.

Since 2020, I’ve designed and built digital products for companies and agencies around the world. That journey has taken me through internships, creative agencies, startups, and my own independent practice, collaborating with 90+ clients.

Somewhere along the way, learning development changed the way I design. I started looking at projects as a whole: how ideas behave in the real world, where problems might surface, and which decisions are actually worth making.

Every design decision comes with a trade-off, so I look at the bigger picture from the start, finding the balance between what’s possible, what’s useful, and what feels right. I believe design is one of the few real levers we have on how people live, so I try to earn every choice.

Today, I bring both design and development to the table: working close to real users and building with teams that keep improving things after launch. AI sits inside every step of the process. I use it to explore more directions, prototype in real code, and test ideas, so I reach the right answer faster.

If you’re building something people will rely on every day, I’d like to hear about it.
