Capability

AI Event Copilot — concept demo

I build AI copilots for live enterprise events: RAG-grounded Q&A generation, knowledge-base chatbots, and agents that query event data on demand. This is an original, from-scratch recreation of those patterns using fictional data — built to show the capability, not a production system.

Generated from the TechConf 2026 knowledge base

AI Agents & 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 AI agent (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.
