Design

I don't just design static visuals; I build living interfaces. Instead of tweaking pixels on an artboard, I design in the browser-obsessing over stylesheets, typography, and fluid layouts to ensure the final experience feels as good as it looks.

Engineering

I specialize in the JavaScript ecosystem, building durable applications designed for scale. Whether it's a complex platform or a quick prototype, I prioritize performance and maintainability, ensuring the code is as robust as the user experience.
