Chang, Chung-Ho

Sr. Software Engineer
Dear HR Manager / IT Manager, I am Chung-Ho Chang, formerly a Project Management Supervisor, and currently a Senior Software Engineer. Within the company, I am responsible for C# and T-SQL program development, with involvement in various types of C# projects. I have developed and maintained standalone programs, web-based applications, WebServices, WebAPIs, big data ETL projects, and automated scheduling systems. I also possess experience in DevOps technologies such as version control and CI/CD. During my tenure at CPC Corporation, Taiwan, I resolved long-standing tax leak issues within systems, boosting report generation speeds by over ten times. Additionally, I addressed abnormal database transaction updates for users and developed a fuzzy query feature, reducing user input time from 1 hour to 20 minutes. I contributed to the establishment of ETL projects for moving data in the big data center, handling 15 million records per cycle. I also served as an internal technical instructor, elucidating advanced features of C#. I optimized database tables for normalization while meeting web presentation needs, enhancing system stability without the need for constant oversight. At Neux, I utilized Java and JavaScript to integrate the Google Maps library and AI shortest path algorithms, providing time-efficient travel routes. My responsibilities included internal system maintenance, Corporate Client System establishment involving HTTPS certificate setup, automated deployment of web applications, creating high-availability architectures, vulnerability scanning patching, and project load testing. My inclination towards problem-solving led me to be among the earliest in the team to master commonly used technologies/open-source software like Linq, Dapper, Newtonsoft, and SqlKata. I prioritize maintainable code, leading to extensive refactoring during my tenure. I find satisfaction when functionalities I develop benefit users, hence my earnest discussions with users about their usage scenarios honed through extensive interpersonal experiences during my military service. In the future, I aspire to deepen my expertise in software development while branching into DevOps and artificial intelligence fields, approaching this with an open-minded attitude. I hope for the opportunity to collaborate with your team and contribute unique value to the company! Best regards, Chung-Ho Chang
