about nico

I'm a Senior Frontend Engineer with 7+ years building scalable web applications across e-commerce, fintech, and enterprise decision intelligence. I specialize in React, Next.js, and TypeScript — with a track record of owning product surfaces end-to-end and delivering outcomes that move real business metrics: revenue, conversion, and adoption.

My strongest work sits at the intersection of technical execution and team clarity. I've led architecture decisions, defined frontend standards, and shipped features that served millions of users across multiple markets — while helping the engineers and designers around me do their best work. I set context, not just tasks, and I measure what matters.

I care deeply about accessibility built into the architecture, interfaces that load fast and stay fast, and code patterns that scale with the team — not just the codebase. I'm moving toward engineering management and Head of Frontend roles where I can combine hands-on technical depth with team-level impact.
