How did Arivihan and AWS build a real-time NEET question AI enrichment pipeline? 

About Company

Arivihan is building India’s first fully automated online learning platform focused on NEET and K-12 education in vernacular languages.

With a mission to make high-quality education affordable for 200M+ students in Tier 2 and smaller cities, Arivihan delivers personalized, interactive learning at nearly 10% of traditional coaching costs.

Challenges

• Ingesting high volumes of NEET questions reliably in real time.
• Decoupling enrichment workflows to avoid bottlenecks and back-pressure.
• Combining foundation models with custom ML inference seamlessly.
• Ensuring least-privilege access and secure AI orchestration.
• Isolating failures without impacting upstream ingestion.
• Managing quota-aware Bedrock and SageMaker usage.
• Establishing observability, CI/CD automation and DR readiness.

Solutions

• DynamoDB + Streams for real-time question ingestion and event triggers.
• AWS Lambda to validate payloads and route questions into subject-wise SQS queues (Physics, Chemistry, Biology) with DLQs.
• ECS Fargate workers (ECR-backed) to orchestrate AI enrichment.
• Amazon Bedrock for explanations, summaries and embeddings.
• Amazon SageMaker for custom inference such as difficulty scoring.
• Amazon S3 data lake (raw → processed → enriched) with versioning and analytics readiness.
• CloudWatch + IAM for observability, governance and least-privilege security.
• CI/CD with CodeCommit, CodeBuild and CodePipeline for automated deployments.
• Terraform-driven DR with DynamoDB PITR and S3 versioning aligned to defined RTO/RPO.
