+Task and Reminder Manager Backend - Walkthrough
+What Was Accomplished
+I successfully developed the backend infrastructure for the Task and Reminder Manager application, exposing a REST API built with FastAPI that meets the user requirements. I set up the database, models, and endpoints necessary to manage tasks and reminders.
+
+Key Changes Made
+Application Structure: Created a modular FastAPI backend (
+main.py
+, 
+database.py
+, 
+models.py
+, 
+schemas.py
+, 
+crud.py
+).
+Database System: Implemented SQLite functionality via SQLAlchemy, with specific models adapted to track user execution and messaging contexts.
+Designed 
+Task
+ model containing the telegram_user_id and the status (pending, completed).
+Designed 
+Reminder
+ model tightly coupled to 
+Task
+, capable of deep tracking: trigger_time, recurrence_type (daily, custom, etc.), and notification toggles (notify_push, notify_telegram).
+Data Validation: Built Pydantic schemas representing creation payloads, updates, and serialized API responses to ensure safe data boundaries.
+API Endpoints: Built isolated routers to handle operations across tasks (
+routers/tasks.py
+) and reminders (
+routers/reminders.py
+). Examples include retrieving tasks specific to a telegram_user_id, handling task completion logic (via PUT endpoint updates), and constructing sophisticated reminders.
+Validation Results
+Verified that all necessary dependencies (including updated Python 3.13-compatible versions) install inside a valid virtual environment.
+Verified successful Uvicorn server boot without errors.
+Fired test API requests to generate entries into SQLite, returning 200 success responses. The system's CRUD functionality handles database commits successfully and retrieves nested relationships gracefully.
