Hello, I am Chih-han Chung.
You can call me Harry.
About me
After graduating with a bachelor's degree from National Taiwan University, I developed an interest in programming. I began learning about cloud and web services, dedicating myself to cloud and full-stack development. I have worked on projects utilizing various AWS services such as Lambda, API Gateway, S3, CloudFront, and DynamoDB. Additionally, I have gained experience with Infrastructure as Code (IaC) tools like Terraform. My favorite aspect of programming is the immediate feedback I receive right after pressing the ENTER key.
I have experience in Agile environments, participating in sprint planning, sprint reviews, and retrospectives. This has improved my collaboration, communication skills, and ability to adapt to changing requirements.
