Developer - Associate DVA-C02

As an AWS Certified Developer - Associate, I have the validated expertise to develop, deploy, and debug cloud-native applications using AWS services. My proficiency covers the entire development lifecycle, from writing code that utilizes AWS SDKs to interact with services, to packaging and deploying applications through robust CI/CD workflows, with a strong focus on serverless technologies.

My technical skills include building fault-tolerant and resilient applications by applying architectural patterns like event-driven and microservices, and implementing asynchronous processing with services such as AWS Lambda, Amazon SQS, and Amazon SNS. I am adept at developing, extending, and maintaining APIs, and I can proficiently use and optimize various data stores, including Amazon DynamoDB and Amazon S3, by implementing effective indexing, caching strategies, and data lifecycle management.

In terms of security, I can implement robust authentication and authorization using services like Amazon Cognito and IAM, manage secrets securely with AWS Secrets Manager, and apply encryption for both data at rest and in transit. For deployment and operations, I am experienced in preparing application artifacts, automating CI/CD pipelines with tools like AWS SAM and AWS CodePipeline, and executing various deployment strategies such as blue/green and canary. Furthermore, I can instrument code for observability, troubleshoot issues using logs and traces from Amazon CloudWatch and AWS X-Ray, and continuously optimize application performance and cost.
