Who I am

I've loved technology since I was a kid. 🚀

It started with online games 🎮. I built things for them, then moved on to websites, software, and even games of my own design 👾.

That passion never left. It's what made software my career, and it still drives me to keep learning and growing in technology.

Things I love

About

I build software that registry offices, banks and field teams rely on every day.

I'm a senior software engineer at Witek, building software for several clients across six stacks. Most of my time goes to ONR, the national operator that runs Brazil's electronic property registration system for registry offices across the country, and to ON-RPCN, which is digitizing birth, death and marriage records nationwide.

Before that I helped a bank take two apps from an empty repository to production, led its frontend team, and rebuilt a large sales app for Unilever in React Native.

What I do

  • Full-stack delivery across React, Next.js, React Native, Vue, Django Ninja and NestJS
  • Design systems in Storybook with clean, well-structured architecture
  • Trunk-based development and continuous delivery on GitHub Actions
  • AWS infrastructure: Amplify, Lambda, CloudFront, DynamoDB, KMS and more
  • SQL and NoSQL data with PostgreSQL, MongoDB and DynamoDB; containers with Docker and Kubernetes
  • Feature flags and monitoring with AppConfig, Datadog, Sentry and Mixpanel
  • Frontend technical leadership and mentoring
