  Frequently Used Tech: Lambda, WAF, Cloudfront, ApiGateway, Kendra, DynamoDB, Pipelines (CI/CD),IAM, Kinesis, Route53, Secrets Manager, Datapipelines, VIP (Load Balancers), Claude (LLM Anthropic model), Websockets, Typescript, Ruby, Python, AWS-CDK, AWS-SDK, OpenApi (Smithy 2.0).Ex: I worked collaboratively to develop a new serverless chatbot and migrate the old chatbot service with approximately 1 million clients. The migration was completed without any downtime and resulted in improved chatbot success metrics (ex: fewer redirections to human agents). It was highlighted in Amazon's Global All-Hands meeting as an example of an efficient AI system as it saved 20,000 hours of human support during 6+ months. Show less
