Launching…
Hi — I'm Sylvester, a designer and developer with a soft spot for interfaces that respect the people using them. I grew up on Windows 98 boot chimes and pixel-perfect toolbars, and that early obsession with how software feels never really left.
Over the past decade I've worked across product design, frontend engineering, and design systems — helping startups find their visual voice and helping enterprises untangle theirs. I care about performance budgets as much as typography, and I believe the best interfaces are the ones you stop noticing.
When I'm not shipping, you'll find me planning family trips, tinkering with side projects, or explaining to my kids why the Windows XP startup sound is objectively a masterpiece.
