What I'm looking for

I'm looking to build maintainable web applications and enterprise systems, especially backend services and REST APIs, while collaborating with agile cross-functional teams to solve real business problems.

I've built and maintained clinical and administrative software at Sisma Corporation, delivering modules for appointments, clinical records, pharmacy, hospitalization, inventory, and accounting.

I use PHP, SQL Server, and JavaScript to turn clinical and administrative requirements into practical software solutions. I also optimize SQL queries, resolve bugs, deliver ongoing improvements, and manage collaborative workflows with Git and Azure DevOps.

At Unicolombo, I contributed to SIGGAP, a university business-internship management system. I built modular Node.js and NestJS backend features, designed REST APIs, and developed Angular frontend functionality including reactive forms, API consumption, and state management.

I'm focused on maintainable code, modular architecture, and solving business problems through software in agile cross-functional teams.
