— Software engineer.
I design and scale backend systems that stay reliable under real load — Ruby on Rails, TypeScript, AWS.
Software engineer with 5+ years building and modernizing systems that run at scale. I led the modernization of a B2B marketplace at Itaú processing millions of transactions a month — including a full Rails 3.2 → 7.2 migration shipped without downtime — and shaped the platform and APIs behind Brazil's largest real-estate marketplace. I work end-to-end: from building resilient backends and pragmatic interfaces to architecting the CI/CD pipelines and AWS cloud infrastructure that support them.
Systems I've shipped and owned.
Led the Rails 3.2 → 7.2 modernization of a B2B marketplace at Itaú processing millions of transactions a month, architecting its initial GitHub CI/CD pipelines and AWS deployment infrastructure.
Owned features and APIs across Brazil's largest real-estate platform, spanning Rails and React/Next.js, with RSpec/Jest reliability coverage and Python pipelines feeding BigQuery analytics.
Designed and shipped the Rails APIs powering a dental-practice SaaS, with RSpec-backed test discipline and OpenAPI contracts that kept integrations predictable.
The stack behind my recent systems.
Itaú Unibanco
Internalized to continue evolving the B2B marketplace platform directly at Itaú, currently focusing on breaking down the legacy monolith into microservices and scaling core backend operations.
BRQ Digital Solutions (Case: Itaú)
Acted on the successful internalization of a high-volume B2B marketplace platform processing millions of transactions a month. Led the full Ruby on Rails 3.2 → 7.2 migration shipped without downtime, and architected the GitHub CI/CD pipelines and AWS deployment infrastructure behind it.
Órulo
Owned features and APIs across Brazil's largest real-estate platform, spanning Ruby on Rails and React/Next.js. Hardened reliability with RSpec and Jest coverage, scaled MySQL and ElasticSearch data paths, and built the Python pipelines feeding analytics into BigQuery.
Dental Office Software
Designed and shipped the Ruby on Rails APIs powering a dental-practice SaaS. Established RSpec-backed test discipline and OpenAPI contracts that kept integrations predictable, working in Scrum/Kanban with OKRs.
PUC Minas
Led the technical design and end-to-end delivery of a complete web platform (Ruby on Rails, Vue.js, PostgreSQL) as the project's engineering lead.
ESL Sistemas
Shipped new product capabilities on a Ruby on Rails and Vue.js codebase and kept its PostgreSQL data layer reliable.
Open to interesting freelance and consulting projects. I read every message and reply within a couple of business days.
