Hi, I'm Isaac Alves 🇧🇷

Ruby on Rails Software Engineer currently building at Umanni (SaaS platform for employee performance and team development).

4+ years of experience specializing in clean code, legacy refactoring, TDD (RSpec), scalable APIs, database optimization and CI/CD pipelines that support multiple daily deployments.

🚀 Currently at Umanni (São Paulo, remote)
Leading refactoring and optimization of performance management modules in a production SaaS environment.

📍 Based in Brazil (fully remote)
📚 Currently exploring Hotwire, advanced backend architecture and modern Rails patterns (Rails 8).

🧠 My journey
Started in infrastructure and automation, transitioned to full Ruby on Rails development. Today I focus on building robust, well-tested systems that deliver real business impact — from legacy Rails 4.2 refactors to modern Rails 8 applications with Docker, Kubernetes and zero-downtime deployments.

Passionate about international collaboration and always interested in new remote opportunities where I can contribute with ownership and growth.
