Admission Intelligence — Academic Data Monitoring & Evidence Engine
Admission Intelligence Platform · 14 weeks · 2 engineers
The Challenge
University admission criteria, fee structures, and scholarship deadlines change frequently across hundreds of institutional web pages without standardized feeds. Manual tracking resulted in stale data, missed application deadlines, and unverified conflicting claims.
Our Solution
We designed an automated admission intelligence pipeline utilizing FastAPI, PostgreSQL, OCR, content hashing, and scheduled change detection. Every extracted record preserves complete cryptographic provenance (source URL, raw text hash, snapshot timestamp, and confidence score) before publishing through an RBAC-protected API.
Outcomes
Measurable Results
Audit
Cryptographic Provenance
Every extracted fact links directly to verified source document hashes and crawl timestamps.
RBAC
Granular Access Control
Multi-role authentication preventing unauthorized modifications and cross-tenant data leaks.
Auto
Scheduled Change Detection
Continuous monitoring of institutional portals with instant notification triggers.
Process
Development Approach
Evidence Schema & Ingestion
Modeled relational PostgreSQL schemas for institutions, programs, crawl runs, and document content hashes to ensure immutable audit trails.
Extraction & Change Detection
Built scheduled background ingestion workers with OCR and diffing algorithms to identify revisions in fee schedules and eligibility criteria.
Security & Access Control
Implemented Role-Based Access Control (RBAC), request validation, and strict API security boundaries preventing Broken Object-Level Authorization (BOLA).
Admin Interface & Test Suite
Developed admin management routers and comprehensive automated test suites covering data integrity, authentication, and endpoint authorization.
