Hospital queues meet an AVL tree
An archived Windows terminal application for patient queues, records, doctors, schedules, appointments, and reviews with JSON persistence.
Bodo models a small hospital workflow in a terminal: patients enter a queue, staff manage medical records, and users maintain doctors, schedules, appointments, and reviews.
The project pairs a FIFO queue for service order with an AVL tree for indexed patient lookup and update. Data is persisted to JSON and restored into the structures at startup.
It is an archived learning project, preserved because it shows the transition from data-structure exercises to a complete stateful application.

I wanted to make queue and balanced-tree operations visible inside a workflow that has users, persistence, validation, and failure cases.
Patient service queue with explicit ordering
AVL-backed medical record search, insert, update, and delete
Doctor, schedule, appointment, and review modules
JSON save and restore across application sessions
Interactive Windows terminal interface with animated feedback
CMake, Ninja, and MinGW build path for C++20
The constraints mattered as much as the finished interface.

Data structures become easier to understand when their invariants are exercised by edits, persistence, and user mistakes.
Archived projects are useful when their limitations and learning purpose remain visible.
