LifeOS
Personal Project (In Development)
LifeOS organizes daily tasks, time estimates, and planning suggestions into a single structured system running locally, with V0.1 and V0.2 completed and V0.3+ scoped as future phases.
- React 18
- TypeScript
- Vite
- FastAPI
- SQLAlchemy 2.0
- Pydantic v2
- PostgreSQL
- SQLite
- Alembic
- Vanilla CSS
Frontend: React 18, TypeScript, Vite, Vanilla CSS Design System (#0B0E14 dark theme) · Backend: FastAPI, SQLAlchemy 2.0, Pydantic v2 · Database: PostgreSQL (Production Target) with automatic SQLite local dev fallback · Migrations: Alembic
My Role & Development
Defined the personal productivity product vision, task management workflows, and deterministic smart daily planning approach across structured versioned milestones, with V0.1 and V0.2 working and V0.3–V0.5 planned.
- Established task priority, scheduling view (Today, Upcoming, Completed), and duration-aware deterministic planning logic.
- Prioritized features across versioned milestones, keeping shipped V0.1–V0.2 modules distinct from planned future phases.
Completed Modules (V0.1 & V0.2)
- V0.1 — Task CRUD, task priorities, due dates and times.
- V0.1 — Today, Upcoming, and Completed views.
- V0.2 — Deterministic planning engine.
- V0.2 — Smart planning suggestions and planning suggestion API.
- V0.2 — Apply suggested plan workflow with estimated task duration.
