Improve package deployment process using step function with shared EFS network file system.
Improve direct file upload process using multipart pre-signed URLs and setup s3 event trigger to invoke the endpoint in ECS spring boot application to post process via private ALB. The response is send back to UI via web socket to update the UI spinner real time. So, we removed public endpoint from API Gateway to prevent invoking the post process endpoint in spring boot application.
Implement idempotency in lambda functions.
Migrate lambda code from Java to Go to achieve maximum runtime performance with minimal cold start time.
Migrate RDS database to DynamoDB to improve query performance and optimise costs.
Implement conversation agent(Innovation Day) to resolve user queries and manage package deployment process using Bedrock multi-agent collaboration and RAG with Open Search Serverless vector database.
Train machine learning models using reinforcement learning for the Deep Racer league.
