AWS fundamentals (Certified Cloud Practitioner)
- SaaS MVP architectures
- Admin dashboard systems
- Automation & bot integrations
- API-first backend systems

Started with WordPress and PHP before moving into modern TypeScript and full-stack JavaScript systems.
That foundation helps me understand both legacy systems and modern architecture patterns.

- Own outcomes, not just tickets
