Breno Pinto

Senior Frontend Engineer

Frontend Engineer with 6+ years of experience shipping high-scale products for companies like Vodafone and WEG. I build fast, accessible, and maintainable interfaces with React, Next.js, TypeScript, and Tailwind CSS — and I'm currently exploring how AI can accelerate frontend workflows end-to-end.

Based in Porto, Portugal. Originally from Pará, Brazil — where I once built a platform to monitor fire areas and seedling growth in the middle of the Amazon rainforest. I speak Portuguese (native), Spanish (fluent), and English (C1). You can find my work on GitHub, connect with me on LinkedIn, or reach me at breno.pereira.dev@gmail.com.
