This repository is the public source for my technical blog.
I write from the perspective of an entrepreneur building and operating real business software with Oracle APEX, PL/SQL, Oracle Cloud Infrastructure, Codex, AI agents, GitHub, automation, and the practical engineering habits that keep production systems understandable and maintainable.
The goal is to share work as it actually happens: what I am learning, what is working, what still needs judgment, and how modern AI-assisted development can be useful without turning software delivery into guessing.
- Oracle APEX and #orclAPEX development in real projects
- PL/SQL, SQLcl, exports, validation, and production-safe workflows
- Oracle Cloud Infrastructure and Autonomous Database
- Codex, AI agents, prompts, skills, and project-specific context
- GitHub-backed engineering workflows and automation
- Lessons from building and improving SaaS products as an entrepreneur
