Sinan Aydın

I develop reliable and scalable applications using Java and Spring Boot. I design, build, and maintain microservice-based systems. I solve problems effectively and work well within a team. I continuously improve my skills by working on real projects and learning new technologies.

I have hands-on experience with AWS services such as S3 and CloudWatch. I use Docker and Kubernetes to deploy and scale applications in cloud environments. I actively use AI tools and agents to improve development speed, debugging, and code quality.
