自傳 Autobiography

 I have more than a 4-year experience in system development and software design (Automation system, MES system, Machine vision, Data science, System refactoring, software architecture design), and I am also passionate about discovering cutting-edge technology in order to see if it can help a company develop more efficiently. I have been professionally using C++ and SQL database for 3 years. Together with the team we have developed Automation system and MES system. The main job of Automation system is to control the whole process of manufacturing a product. I have added some functions to the system and I have also enhanced its efficiency. As for MES system, main function is to schedule the next task for every machine, I have been responsible for providing necessary maintenance and improving the overall performance of the MES system In 2019, I transferred to Data Science team of IT department. Since I had the previous experience of manufacturing, I started using data from factories to perform data mining, data analysis as well as modeling based on machine learning. One of the projects that I have led from the very beginning aimed to use the power of the AI to do visual inspection: before we provide a solution to an operation site, a factory machine operators can use AOI (Automated Optical Inspection) machine to detect any defects of the product. Our goal is to aid the operation site to perform more efficiently by providing a more accurate way of inspection than the typical AOI machine, it also helps to run this operation without extra workforce. with the help of this project, I can work with other company's team smoothly, and we have started using the scrum master development to trace each member's progress, as a result, we deliver the most suitable solution to the operation site successfully. One of the achievements of this project has been the reduction of the overkill rate from 20% to 6.7%.
