Full-stack commerce platform for a dental supplies distributor in Chiapas.
Two simultaneous channels from one codebase:

Both channels share the same product catalog, inventory, customer accounts, loyalty points, and order history — synced in real time via Firestore.

Notable implementation details:

• Server-side price validation — Cloud Functions read prices from Firestore; clients never supply amounts
• Loyalty points with atomic Firestore transactions — no race conditions
• Partial fulfillment workflow with per-item delivery tracking
• Cash drawer management: opening balance, movements log, session close
• Multi-role system: admin · seller · user
• Firestore security rules block direct client writes to all financial fields

Browser-based platform for comparing two 3D scans of the same physical site across time. Load two models, align them mathematically, measure the differences, and export a professional PDF report.

Key technical decisions:

• Split-screen viewer with bidirectional camera sync — RAF loop, not OrbitControls events
• Kabsch rigid-body alignment with Jacobi SVD — implemented from scratch, no external linear algebra library
• Alignment transforms stored as number[16] (Matrix4 elements); Three.js objects never enter React state or Zustand
• Four measurement tools: point-to-point distance, surface area, cross-model delta, volume difference
• AI-generated change detection and report narratives via Claude API
• PDF export with jsPDF + jspdf-autotable
