Personal OS: The Warborn OS Subsystem

Problem

Developers often use fragmented applications to manage notes, checklists, budgets, and API prompt testing. This causes context-switching delays and data fragmentation across third-party services.

Solution

We built an integrated workspace dashboard (Warborn OS) nested inside a unified Next.js monorepo. It connects note-taking, habit trackers, and local AI workspaces through a single session authentication model.

Architecture

  Next.js 15 Client (Zustand & React Query)
                 │
                 ▼
  FastAPI Backend (SQLAlchemy / Alembic)
                 │
                 ▼
  PostgreSQL Database (Supabase with RLS)

Technical Decisions

• Next.js & React 19: Chosen to support both static marketing pages and the dynamic, authenticated developer dashboard.
• FastAPI (Python): Handles compute-intensive operations, file parsing, and integrations with Python-first AI frameworks.
• Prisma & Alembic: Manages database migrations across the monorepo cleanly.

Results

• First-load JS weight optimized to 103 kB (under the 120 kB ceiling).
• Workspace action response times reduced to under 50ms using optimistic state updates.
• Centralized all developer tracking metrics into a single, secure database.

Future Roadmap

• Local vector search integration for notes using pgvector.
• Automated script runner tracking.
• WebRTC voice interfaces for prompt evaluations.
