Senior Full-Stack
& Cloud Engineer.
Senior full-stack and cloud engineer with 8+ years of experience, currently the sole owner of the AI platform at Nova Dynamic Media, a live-events company. I care about reliability under real pressure over features that only work in a demo, and I've led development teams of 3 to 8 people while staying hands-on with architecture and code rather than stepping back into pure management.

RAG, Agents & Real-Time Systems
The hardest and most involved work I have built: a production AI platform for live enterprise events — RAG copilots, agentic workflows, and real-time interaction, owned end to end. It is one part of what I do, not the whole of it.
RAG and agentic workflows on AWS Bedrock, with real-time interaction on AppSync. Every answer is grounded in real event data, autonomous agents reason over live metrics and audience questions, and thousands of attendees stay in sync at once. I own it end to end, from the vector knowledge base and the moderator copilot to the summarization and reporting pipeline.
- RAG system on AWS Bedrock grounding answers in event data
- Agentic workflow for querying live metrics in plain language
- QnA grouping and AI report generation, now on Amazon Bedrock AgentCore (building)
- Moderator copilot generating and answering audience questions live
- Live and post-event chatbots plus livestream summarization
- AWS AppSync + GraphQL real-time Q&A, polls, surveys, and quizzes
- Migrated from IoT Core/MQTT to AppSync for better scale

Agentic Workflows & RAGReal‑Time Interaction at ScaleAWS Cost Optimization
- Sole owner of the AI platform: a production RAG system on AWS Bedrock (S3 Vectors, hierarchical chunking, semantic search) powering a live moderator copilot and post‑event AI assistants with source‑backed answers.
- Own the agentic AI layer end to end — a natural‑language event‑metrics agent (query generation, validation, reasoning steps), automated QnA grouping, and AI report generation — now running on Amazon Bedrock AgentCore with infrastructure provisioned via Terraform.
- Cut throttling failures 60–70% under burst load with cross‑region Bedrock inference failover and exponential backoff, keeping the live copilot responsive at peak.
- 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.
- 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.
- 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.
- Mass email system: SQS queues import users into the platform, a Step Functions workflow adds them to Mailgun mailing lists (primary provider), with AWS SES as backup.
- Live video transcription and translation with real‑time captions in each viewer's own language.
- 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, multi‑account, cross‑region releases across microservices.
