About me
I'm Duy, an Oracle-certified APEX developer (1Z0-771) building and maintaining internal Oracle APEX applications in the banking sector.
I turn spreadsheets and slow manual processes into secure, fast APEX apps: asset and inventory systems, approval workflows, dashboards and reports.
I use AI-assisted development on APEX 26.1 with a strict review process (security checks, validated imports, Git), so you get speed without sloppy code.
Live demo available. Message me with your APEX version and what you need. I usually reply within a few hours (GMT+7).
