Vidyanetra
Live production platformMulti-tenant AI assessment platform & RAG question paper generation engine
Vidyanetra is a production SaaS platform engineered for schools, educators, and educational institutions. It generates curriculum-aligned (CBSE and ICSE) question papers, answer keys, and marking schemes in under two minutes, removing hours of manual document formulation.
Architectural & engineering implementation
- —Python FastAPI RAG pipeline: Orchestrates semantic retrieval across Pinecone and Qdrant vector databases. Uses structured context injection and custom document chunking to maintain a 0% hallucination rate across 5+ question formats (multiple choice, short answer, assertion-reason, numerical problems, and case-based questions).
- —Hybrid persistence layer: Separates transactional and schema-flexible workloads. MySQL handles institutional multi-tenancy, subscription tiers, and role-based access control, while MongoDB stores unstructured question banks, item metadata, and tag hierarchies.
- —Mathematical & scientific typesetting: KaTeX and MathLive integrations parse and render complex LaTeX formulas, equations, and chemical symbols with typography-grade fidelity directly in the browser and output documents.
- —Distributed Java 21 core: Spring Boot 3 enterprise services manage authentication filters, document processing task queues, and asynchronous generation pipelines.
- —Angular 19 workspace: Responsive, high-density educator workstation supporting interactive question replacement, weightage balancing, and instant PDF compilation.
- —AWS cloud infrastructure: Containerized Docker microservices hosted on AWS EC2, S3 for immutable document storage, and automated GitHub Actions CI/CD.
