My Journey to Becoming an AWS Certified Developer Associate

Breaking into cloud computing has been one of the most rewarding steps in my career journey. With more businesses moving to the cloud, I knew I needed to strengthen my understanding of AWS and how developers can build, deploy, and maintain applications at scale.

Preparing for the AWS Certified Developer – Associate exam pushed me to go beyond theory and really dive into how AWS services work together. From writing serverless applications with Lambda, managing messaging patterns with SQS and SNS, to securing applications using IAM and KMS, each study session added new layers of practical knowledge I could apply directly to projects.

I also gained confidence working with developer-focused tools like CloudFormation, API Gateway, DynamoDB, and CI/CD pipelines using CodePipeline and CodeBuild. Beyond just passing the exam, this journey reshaped the way I think about building scalable, resilient, and secure applications on AWS.

But this is just the beginning. My next steps are clear:

  • AWS Certified SysOps Administrator – Associate: to deepen my operational knowledge of monitoring, automation, and cost optimization in AWS.
  • AWS Certified Solutions Architect – Professional: to master designing and scaling complex systems in the cloud.

Earning this certification has been a milestone, but I see it as a foundation for even greater expertise ahead.
