My technical foundation

I hold a Technical degree in Computer Science and I'm finishing my Bachelor's degree in Computer Science at UTFPR — Universidade Tecnológica Federal do Paraná, one of the largest universities in the state. This technical foundation is what supports the way I work, from well-written code to every architectural decision in each project.

My story

I started my career in 2018. At first, my focus was simple: build applications that worked well. I went deeper into front-end development with React and Next.js, and started working on increasingly complex projects — from web platforms to mobile apps.

Over time, I realized that good code goes beyond just working. I started pursuing performance, clean code and a product experience that makes a real difference for the end user. This obsession with technical quality drives every decision I make.

How I work

01

Component architecture

I create reusable, well-structured components. Every interface is designed to scale without compromising code maintainability.

02

Modern technology

I work with React, Next.js, TypeScript and PostgreSQL, always aiming for fast, type-safe and scalable applications.

03

Performance from the start

Performance and accessibility are part of the project from the ground up, not as a last-minute fix. The result is fast and accessible by default.

04

AI applied to delivery

I use artificial intelligence to speed up delivery, with Claude Code and GitHub Copilot. In practice, that means more agility without any loss of quality.

What I do

Web interfaces

React and Next.js applications focused on performance, accessibility and user experience.

API integration

Connection with external services, REST and GraphQL APIs with robust data handling.

Platforms

Scalable, well-built web applications.

Mobile apps

Cross-platform apps built with React Native.
