// Hi, I'm Gadiel Muñoz
Oracle APEX & PL/SQL Developer
I design and build the system that runs your business: an ERP with the modules you need, connected through REST APIs to everything you already use, and powered by AI. I deliver faster without lowering the bar on quality or security.
Three ways I can help
All held to the same standard: reviewed code, security built into the database, and documentation your team can maintain.
Your company's core system, built on Oracle APEX and Autonomous Database, with the modules your operation needs. I design it around your processes, not the other way around. I also modernize and tune existing systems: PL/SQL re-engineering and fast queries.
Your ERP doesn't live in isolation. I connect it with everything you already use: other ERPs like SAP, banks, tax authorities, logistics platforms, GPS, WhatsApp Business and maps. I design and expose REST APIs, and SOAP when needed.
Inside your data: semantic search and assistants that answer from your documents with Oracle AI Vector Search, without your data ever leaving your database.
In how software gets built: I develop with AI agents to deliver in less time, while I own the architecture, review and security.
// Quality & security: built with AI doesn't mean built carelessly
Security testing and code review before production.
Permissions enforced in the database, not just hidden in the UI.
Separate DEV · PRE · PROD environments and version control.
Documented standards so your team can pick up the work.

AI as my team, my judgment as the filter
Before any code, I lock down what gets built and how it should behave.
I orchestrate agents that work against documented standards: naming, security, structure.
Compilation, tests, code review and security testing. What doesn't pass doesn't move forward.
Nothing reaches production without human review. Separate environments, everything versioned.
→ Faster delivery, with senior-team quality.
I started with numbers: I trained in accounting and worked at an accounting firm before moving into software. Since 2023 I have been building enterprise solutions on Oracle: first leading ERP implementations, then developing complete ERPs and CRMs, and today working remotely for a logistics company in Spain. That background is my edge: when I design a sales or finance module, I understand the business process behind it.
