What I'm looking for

I’m looking to build performance-driven, scalable enterprise products—Oracle APEX/PLSQL, clean REST APIs, and cross-platform apps. I want a team that values maintainable code and ships reliable features end to end.

I’m a Full Stack Developer with 2+ years building and maintaining enterprise systems on Oracle. I specialize in PL/SQL development, Oracle APEX applications, and REST API design with Oracle ORDS, plus reporting that keeps business operations reliable and on time.

I’ve shipped cross-platform mobile apps with Flutter—published on both Google Play and the Apple App Store—and I focus on performance, scalability, and clean, maintainable solutions. In my current role, I build Oracle APEX and PL/SQL backends, deliver REST APIs with Oracle ORDS, integrate with Node.js/Express for pipelines, and implement reporting with JasperReports/JasperServer, including complex modules like bank reconciliation with fuzzy matching.
