Mauro Muller is a veteran systems analyst and developer with roots in computing dating back to 1982, bringing decades of hands-on experience from BASIC and COBOL to modern Java EE, PL/SQL, C# and BI toolchains. He has led multiple full-cycle migrations and rewrites—moving legacy PL/SQL systems to Java EE stacks (Tomcat/WildFly, Hibernate, JSF/PrimeFaces) and modernizing deployments on Linux and virtual servers with PostgreSQL. Comfortable across databases, networking, servers and Dev environments, he blends deep practical knowledge of older infrastructure (DOS, Novell) with current cloud-adjacent, low-cost virtualization strategies. Known for finishing what he starts, Mauro pairs a pragmatic, cost-conscious approach with continuous learning—recently embracing IntelliJ, CDI and Java web ecosystems after decades in Oracle/PLSQL. Based in Rio Grande do Sul, Brazil, he currently applies this breadth at GVD International Trading S/A, delivering reliable BI and web solutions from data ingestion to production.
