FRONTEND ENGINEER — REACT · TYPESCRIPT

I build and architect scalable, high-performance web applications — with accessibility and code quality as defaults, not afterthoughts.

I'm a frontend engineer specializing in building and architecting scalable, high-performance web applications with React, TypeScript, and modern JavaScript tooling. Currently at Marqii (US), I own frontend solutions that power restaurant dashboards, embeddable widgets, and real-time integrations — always aiming for architectural integrity and measurable business impact.

My background in EdTech at Trybe and Rocketseat sharpened my technical depth and mentorship: I've helped 200+ developers level up, and I bring that same focus on clean, maintainable architecture to every team I join.
