Adriano Dos Santos Fernandes is a seasoned software developer with 21 years of experience based in São Paulo, Brazil, currently contributing to the Firebird Foundation. He combines deep backend expertise in PL/SQL and performance optimization—demonstrated by work on the PL/JSON library—with modern web and integration skills using Java, React/TypeScript, GraphQL and Docker. Adriano has led major ERP migrations from Oracle Forms to web architectures, re-architected legacy EAV databases, and built CI/CD and DevOps workflows for production reliability. Longstanding involvement with the Firebird open-source project includes modernizing internationalization and SQL/PSQL subsystems, reflecting both code-level problem solving and architectural vision. He frequently balances hands-on coding, code review and team mentoring, and brings a pragmatic focus on efficiency (avoiding unnecessary object copies and pre-parsed paths) that yields measurable performance gains.
