Front-end Developer·Minas Gerais, Brazil
Hi! I'm Luiz Felipe, a Front-end Developer based in Minas Gerais, Brazil, currently at Grupo Plan Marketing. I've shipped products across health, media, and Web3, always chasing the details that make interfaces feel clearer and faster.
My work lives between design and engineering — I care as much about how an interface behaves and performs as how it looks. Mainly TypeScript, React, Next.js, and Tailwind CSS, staying close to the design side with Figma.
On the side I build small open-source tools like Memojs, Motiro and Tailugin, where I explore reusable APIs, developer experience, and clean, reusable code.
Where I've worked and the sites and apps I helped ship in health, media and Web3. Most of them can't be linked anymore, so each one says why.
Building and maintaining web and mobile apps for Pincéis Atlas, a Brazilian paint-tools manufacturer, with a focus on performance, code organization and scale.
Improved Web3 services, working across the front end and the back end to make them sturdier, more accessible and easier to scale.
Built the mobile app for GoldCare Health & Wellness, a health and wellness platform, alongside the web front-end work at RBR Digital.
Built web front-ends for news and health platforms, delivering accessible content on current events.
Built and maintained front-end services and apps for small projects and businesses while consolidating modern development practices.
