What I'm looking for

I'm open to opportunities as an Oracle Developer, Oracle APEX Developer, or PL/SQL Developer.

Oracle Developer specialized in PL/SQL and Oracle APEX, with experience developing and supporting SCAE, a system used by one of Brazils largest sanitation companies to manage water meter readings, calculate water/sewage consumption, and generate invoices (NFC/NFA) for national utility providers.I have a track record of delivering results with direct business impact: reduced SLA-breaching ticket backlog by 50% in just 1.5 months (from 300 to 150 tickets, including requests and incidents), through the refactoring of critical PL/SQL objects.

Additionally, I participated in the full migration of an HR system from Oracle Forms to Oracle APEX, modernizing the interface and processes without disrupting the clients operations.

Day-to-day, I work with:

• Backend development 100% in PL/SQL: procedures, functions, packages, triggers, jobs, indexes, and performance optimization of queries and views

• Development of screens and modules in Oracle APEX • Integrations via REST APIs and scheduled jobs

• Version control with Git and continuous deployment (CI/CD) via Azure Pipelines

• Generation of fiscal documents (NFC/NFA) with Jasper Studio/Jasper ReportsOpen to opportunities as an Oracle Developer, Oracle APEX Developer, or PL/SQL Developer.
