Prior stack: PHP WordPress AngularJS

Coming from 7+ years of PHP/WordPress/AngularJS freelance work, I've spent the last two months rebuilding deep backend fundamentals in Python — one project a day, fully documented:

• Days 1–10: Python basics & OOP
• Days 11–19: FastAPI core — CRUD, SQLAlchemy, JWT auth, role-based routes, testing, first deployment
• Days 20–33: Capstone build — full backend, AI integration, testing, React frontend, deployed live
• New project: Inventory Management System — Docker, RBAC, CRUD with production-style validation

• developer_journey_2026 — the 90-day return-to-dev roadmap
• student-grade-analyzer series — early Python OOP progression through modular CRUD architecture
