5 years in software development

From hospital maintenance to production systems.

My career began in a technical role, maintaining, calibrating, and troubleshooting hospital equipment. In 2022, I started working as a freelance developer and turned that problem-solving foundation into a software career spanning backend, frontend, infrastructure, and deployment.

2021 — 2022

Hospital equipment maintenance

Worked at Medical Center and Engebio Nordeste on preventive, predictive, and corrective maintenance, as well as the calibration of infusion pumps, ventilators, and multiparameter monitors.

2022 — 2023

Freelance work and transition into software

Started with freelance Full-Stack projects and later developed systems for SEJUS using Laravel, React, and Docker, including a socioeconomic assessment solution.

2023 — present

Public-sector systems and technical leadership

At DER/RO, I progressed from developer to Head of the Systems Development Unit, leading solutions such as SGI, SADER, Geoportal, Passe Livre, and the Document System.

Technology serving operations and people.

I am a Mid-Level Backend Developer with Full-Stack experience, based in Porto Velho, Rondônia, with five years of development experience. I work on business and government systems that require clear rules, service integration, and accountability in production.

My work combines development, maintenance, infrastructure, and direct contact with operations. I like to understand the complete process and deliver solutions that keep working after release.
