Agentic Workflows & RAGReal‑Time Interaction at ScaleAWS Cost Optimization
- Real‑time audience interaction (live Q&A with upvoting and direct replies, speaker teleprompter, polls, surveys, quizzes, synchronized slideshows) built on AWS AppSync + GraphQL + DynamoDB — migrated from the older IoT Core/MQTT setup for better scale. 50+ productions.
- AI moderator copilot built on an AWS Bedrock RAG system (event content indexed into a vector knowledge base) that generates, groups, and answers audience questions live.
- Live AI chatbot for audiences + a post‑event AI chatbot for asking about the presentation, on the same RAG system.
- Livestream summarization and AI‑driven insight reporting.
- An agentic workflow (AWS Bedrock) for querying live user metrics in plain language as an alternative to report generation.
- Created Mission Control, a unified moderator dashboard.
- Telemetry pipeline: Kinesis Firehose → S3 for storage, Redis/Valkey for live stats; processed with AWS Glue + Athena for reports and AI insights.
- Live video transcription and translation with real‑time captions.
- Encrypted stored video and reports with AWS KMS.
- QR‑based check‑in app built with Flutter, plus attendance reporting.
- Secure HLS delivery with token‑based encryption/decryption and access control; migrated 1000+ videos to adaptive HLS with AWS MediaConvert, improving quality and reducing bandwidth.
- Cut cloud spend by ~40% via Lambda Graviton migration, EC2 right‑sizing, and DynamoDB capacity tuning.
- Migrated CI/CD from Jenkins to AWS CodeBuild for consistent releases across microservices.

AI Event Copilot
I build AI copilots for live enterprise events — RAG-grounded Q&A generation, knowledge-base chatbots, and agents that query event data on demand. I put together an interactive, client-side demo of those patterns (fictional data) so you can try it yourself.
