Jheng Guo Lee (Cletus Lee)

I am a software craftsman. With over 8 years of experience, I have designed different frameworks and workflows for data migration and web development using the best practices of agile development. I integrated automated unit testing, functional testing, version controlling, code quality checking on the Jenkins servers across projects. The agility gaining from the continuous integration process significantly increases the productivity during the development. Except the software development skills, I also have a deep understanding of both Scrum and Kanban.


I want to obtain a senior engineering role. Seeking for opportunities not only for a development position, but also helping the team to achieve the full potential of teamwork.
