// EXECUTIVE SUMMARY

Evaluates handwritten STEM notebooks step-by-step down to mathematical/physics formulas via Gemini 2.0 Flash Vision / GPT-4o, flags peer copying in sub-seconds, and provides a 24/7 Socratic AI tutor.

// B2B & ENTERPRISE VALUE PROPOSITION

White-label wildcard-subdomain (*.omnicheck.kz) SaaS for K-12 school networks and prep centers that cuts teacher grading workload by 80%+ while guaranteeing strict student PII privacy.

1. The Challenge

Manual grading of handwritten STEM notebooks drains hours of teacher capacity daily, while uploading raw notebook photos with student names to cloud LLMs violates GDPR/PII laws and deadline spikes crash synchronous servers.

2. Architectural Solution

Engineered Next.js Edge Middleware for wildcard subdomains and 6-tier RBAC, client-side HTML5 Canvas compression (15MB -> 250KB) with Top-7% header auto-masking (Privacy Shield), Sharp perceptual dHash plagiarism detection, and asynchronous Redis + BullMQ Vision AI workers.

3. Measured Outcome

Zero PII exposure to external LLMs, sub-second peer plagiarism detection (>85% Hamming similarity), 3-tier AI model fallback guaranteeing zero 500 errors during deadline surges, and Kundelik.kz CSV export.

Key Engineering Highlights (For CTOs, Recruiters & Systems Architects)

Edge Middleware & License Gatekeeper: Wildcard *.omnicheck.kz routing, 6-tier RBAC hierarchy, and instant license state enforcement.

Client-Side Privacy Shield (GDPR): HTML5 Canvas masks the top 7% PII header and compresses 15MB photos to ~250KB before upload.

Perceptual dHash Anti-Plagiarism: Sharp 64-bit difference hashing flags copied notebooks across classmates in <1 second.
