Building maintainable products

I’m a full-stack developer based in Brazil. I work across mobile, backend, and web development, with a focus on software that stays understandable as it grows.

My core stack is Flutter, Django, and PostgreSQL. I also use Astro and Next.js for web projects, plus Docker and Google Cloud for delivery and operations.

Since 2022, I have developed and maintained mobile and web applications at the University of Caxias do Sul. That work includes the university’s official app and collaboration with developers and stakeholders across the product lifecycle.

How I work

  • Model the domain before choosing abstractions.
  • Keep architecture explicit and dependencies replaceable.
  • Prefer small, reviewable changes backed by automated checks.
  • Measure performance before optimizing.
  • Document decisions that future maintainers need to understand.

Current focus

I’m deepening my work in automated testing, continuous delivery, and product observability while continuing to ship Flutter and Django applications.
