I learn how to be a better software developer when I work in CHT. I started as a junior engineer who didn't have software development experience to be a software developer who can design and implement the whole system by himself. The following projects were I participated in: A. Information Sharing and Analysis Center (ISAC) In this project, I work with a team composed of different companies. We used the bottom-up approach to design the system. Each member focus on developed the module they responsible, and discussed with other members how to build the API integration.

Firewall policy management system (FireExpert) FireExpert was a new product development project by another engineer and me. In this project, I introduced and implemented the ISAS development process method into FireExpert development and responsible for the system architecture design and made sure each module was right. Skill: Java, Spring Boot, Spring JPA, Spring Security, Vue.js, Gitlab Member: Developer: 2 Work Content: Design: 50%, Develop:30%, Test:20% ============================================================================================= C. Asset management and risk assessment system In this project, I was responsible for the whole system development, including the system architecture design, requirement analysis, unit tests, software deployment, etc. This product was originally a simple tool developed for a certain project. While the product developed, I think this tool can become a powerful product, so I used a more flexible design pattern to implement each module. Finally, I made this tool adapt to different company asset management methodologies and helped my company get a tender of NTD$35,000,000 from the government.

Punch Clock App on Microsoft Teams - a collaborative project with Microsoft This product is a Microsoft Teams application plugin from a collaboration case with Microsoft. In this case, I responsible for finished the prototype application from Microsoft. I needed to improve security issues and complete advanced features. I also needed to integrate the customer's Azure AD data into this application and built the Azure Authentication flow by Microsoft Teams SDK.
