Java Backend Engineer 

  Taipei City, Taiwan

Hello, I'm Ken, a Java developer. I have extensive experience in utilizing Spring Boot and Postgres to develop systems. I've worked in small companies with fewer than 50 people, where I've been involved in both independent development and project maintenance. Additionally, I have experience in the banking industry, particularly in conducting vulnerability scans, patching, and stress testing for security purposes.


In my current role, I primarily focus on back-end development for a store management system using Spring Boot and Postgres. I also manage a data centralization system composed of Apache Spark and Kafka.
