Proven experience developing applications in AWS, including ECS, Aurora PostgreSQL, SQS, and EventBridge.
Strong SQL skills with experience in transactions, locking, query optimization, and indexing.

Experience building and maintaining automated testing frameworks using JUnit 5.
Familiarity with Git, CI/CD pipelines, and modern software development practices.
