About me

An engineer who sweats the details.

I'm a 31-year-old engineer building high quality mobile apps across iOS, Flutter and React Native, with a focus on reliability, maintainability and clean software design. I'm currently a Lead Software Engineer at ZAR, an a16z-backed fintech building USD stablecoin wallets and a merchant network for emerging markets.

Over the last couple of years I've gone deep on AI-native engineering: I design and run autonomous AI agents, and I've shipped AI-powered products end to end. Testing stays fundamental to how I work; I'm a strong advocate of Test-Driven Development.

I'm a creative developer who loves playful micro-interactions, with a deep love for beautiful UI, intuitive UX and a sharp attention to detail.

Words I work by

I believe great products come from clarity, empathy, and relentless attention to detail.

— Rayan

The details are not the details. They make the design.

— Charles Eames

Design is not just what it looks like and feels like. Design is how it works.

— Steve Jobs

Perfection is achieved not when there is nothing more to add, but when there is nothing left to take away.

— Antoine de Saint-Exupéry

AI does not replace craft. It raises the bar for what one engineer is expected to ship.
