Summary
The Zero-PII Neighborhood Blue-Collar Trust Platform Backend is an asynchronous API engine engineered to solve the trust deficit between homeowners, village associations, and informal blue-collar service workers (electricians, plumbers, carpenters, cleaners) in Philippine residential communities.
Rather than storing sensitive personal documents (such as government IDs, home addresses, or NBI clearances), the platform implements a Zero-PII verification architecture: it validates claims against simulated government attestation endpoints and stores only cryptographic hashes, public reputation signals, and dynamic TrustScores.
Homepage & Feature Highlights
- Dynamic TrustScore Engine (0–100): Computes multi-factor trust ratings based on completed jobs, client ratings, biometric attendance, and eGov verification credentials.
- Cryptographically Signed Gate Passes: Issues tamper-proof, time-bounded JWT QR passes (RFC 7518) that security guards at subdivision checkpoints can verify offline in under 100ms.
- Zero-PII Verification Model: Stores cryptographic attestation proofs and HMAC verification tokens without ever persisting raw Philippine Identification System (PhilSys) data.
- Async Performance: Powered by FastAPI, SQLAlchemy 2.0 (async), and PostgreSQL with automated connection pooling and sub-5ms API latency.
