Frontend Engineer — Architecture, Design Systems and Interaction

Beyond
The Surface

I'm a Frontend Engineer focused on building complex interfaces and the scalable systems behind them.

My background spans enterprise B2B platforms, Microfrontend architecture, and comprehensive Design Systems. I thrive where engineering meets interaction, bridging the gap between structuring a robust architecture and crafting an experience that feels perfectly tuned in the browser.
