01 // Engineering & Operational 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.

02 // 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.

03 // Verified Production 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.

04 // B2B Commercial & ROI Value

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.
