SQLModel over SQLite
instead of Separate SQLAlchemy models and Pydantic schemas
At this size, one set of typed models serving both persistence and validation removed a whole class of drift between the database and the API contract.

Focus Flow
Full-stack deep-work assistant
The problem
A vague task is the reason deep work never starts. 'Write the report' has no obvious first move, so the session gets postponed.
What I built
A full-stack productivity app that breaks a vague task into concrete steps with rough time estimates, then tracks focus sessions against them and reports on recent focus time.

SQLModel + SQLiteHighlights
- REST endpoints for task decomposition, focus-session tracking and usage statistics.
- SQLModel over SQLite, so typed models are shared between the ORM layer and request validation.
