At Multitherm Sistemas e Automação, I built product features for Gestum, a SaaS ERP for production planning, inventory, and finance. It served more than 1,000 users across 90 textile manufacturers.
I owned production operations as the sole engineer on call, managing AWS and on-premises infrastructure, deployments, security, and incident recovery. I also built integrations that synced about 2 million machine readings per day from more than 1,300 devices.
I built a Python conversational AI assistant used daily by 200 executives to turn natural-language questions into read-only PostgreSQL queries. It replaced custom reports that had required weeks of development, with access controls and query auditing.
Earlier, at Governança Brasil, I built a shared internal component library and converted legacy VB6 systems to Java EE and Angular. As a DevOps Engineer, I owned internal engineering tooling, including a self-hosted GitLab instance used by 5,000 developers.
