Who Am I?
Karla Fernandes

I teach you how to design, build, and ship digital products as a team of one, using AI where it matters most. I simplify the path from idea to market through process, strategy, experimentation, and clear results.

I have spent 25+ years building digital products end to end. My work combines UX/UI design, digital product strategy, and hands-on execution.

I design interfaces, build systems, ship products, and teach others to do the same. I have collaborated with startups, tech companies, educational organizations, and service-based businesses across the globe. Read my full story →
