I'm Munir Mahmud — an Oracle APEX architect and DBA with 20+ years of hands-on experience building and running enterprise Oracle systems. I don't just write code — I architect complete Oracle solutions, from database design and PL/SQL engineering to APEX application development and cloud deployment on Oracle Cloud Infrastructure (OCI). What makes me different from most Oracle developers: I've personally built and deployed a full production APEX application (Vobon Apartment Management System) running live on OCI — handling real users, real transactions, and real business operations. You can explore a live demo at vobon.xyz ([email protected] / ateam123). What I deliver for clients: ✅ Oracle APEX application design, development & deployment ✅ Oracle Database performance tuning (AWR, ASH, execution plans) ✅ PL/SQL engineering — packages, bulk processing, optimization ✅ Oracle EBS R12 integration — Order-to-Cash, AR, GL modules ✅ OCI deployment — ORDS, Apache Tomcat, SSL, Oracle Wallet ✅ REST API integration with APEX and Oracle Database ✅ ERP dashboards and financial reporting ✅ Database backup & recovery — RMAN, Data Guard I've worked across manufacturing, real estate, finance, and ERP sectors — always focused on systems that perform under real business pressure, not just demos that look good in testing. Response time: 0–4 hours. Available for both short-term projects and long-term engagements. Let's talk about what you're building.
