Message

At Balance of Nature, I developed an AI-powered code review microservice integrated with GitLab Merge Request webhooks. It analyzes diffs, masks known secrets, and publishes suggestions; developers adopted suggestions on selected projects.

At Lumiun Tecnologia, I conceived and implemented almost the entire white-label architecture for Lumiun DNS, enabling brand customization, data isolation, customer-specific policies, and access control. I also evolved Stripe subscription and payment workflows and optimized database queries for dashboards.
