What I'm looking for

I seek roles focusing on security, performance, and system design with opportunities to improve CI/CD, automate deployments, and grow in security and architecture.

I am a Ruby on Rails developer with five years of professional experience building and modernizing web applications, focusing on security, performance, and automation.

I led upgrades from legacy Rails versions to modern stacks, implemented SSO, feature flags, websockets, and expanded test coverage using RSpec, Capybara and Selenium to improve reliability.

I designed CI/CD pipelines, integrated security tooling such as Trivy and rubocop hooks, and configured build and reverse-proxy environments to streamline deployments across projects.

I hold masters in Data & Big Data Architectures and in Software & Mobile Development, and I am eager to grow my skills in security, performance, and system design while contributing to robust production systems.
