The project architecture uses a microservice architecture, and the language uses Java (Spring boot/cloud). Two platforms are planned based on whether the data is real-time or not: 1. For the small amount of data and high real-time demand: The data of a large number of equipment in the factory can be uploaded to the system, and the data can be stored and displayed on the front end in real-time. The main technologies used are MQTT, Kafka, TSDB (Influx), Redis, and WebSocket. 2. For a large amount of data and low real-time demand: This part is mainly to process the data with high sampling frequency and store it in HDFS for subsequent analysis and AI use. In addition to the Hadoop ecosystem, it is also used for Python to analyze and process data. Main daily work: 1. Lead the project members to jointly implement the prototype of the system. 2. Manage software development process (including product planning, architecture design, system development, and testing). 3. Communicate with customers during the project development process and transform customer needs into specifications that can be implemented and developed by engineers. 4. Appropriately introduce new technologies, and teach and improve the professional capabilities of engineers. Achievements : 1. The system was exhibited at the Shanghai National Convention and Exhibition Center in 2018 and the International Plastics and Rubber Industry Exhibition in Taipei Nangang Exhibition Hall. It not only enhances the company's image in Industry 4.0 but also Increases sales of injection molding machines by 10-15% in the year. 2. The system will be officially sold to Taipei Veterans General Hospital in 2020. It will be introduced to other Veterans Hospital systems in the future, which is estimated to increase the company by 150 million. Revenue of more than 10,000 yuan (each set sells for more than 10 million yuan, 3 general hospitals plus 12 branch hospitals, totaling 15 hospitals).

Leading the company's product planning, design and development in the Andriod system application program, through studying the MQTT protocol and the open source project Eclipse Mosquitto, designing a robust MQTT communication mechanism to improve the communication quality between IoT devices.

Responsible for the planning and development of the Android application of the company’s stock products, improving the user experience that is not good when drawing stock price charts when the amount of data is large, especially when running on low-hardware devices.

1. Developed the first digital TV with operating system and network functions for the company, which enabled the company to obtain orders from many major TV manufacturers in mainland China. In addition to sales, sales of high-end Internet digital TVs have also been increased. 2. Responsible for the maintenance and quality assurance of the company's public version of the program, and lays a complete program code entry and testing process for the company.

Responsible for writing the CIM system software. During the work, there was a requirement change plan for Guanghui Longtan Factory. Originally, the project manager estimated that it would take one month to develop. With careful observation of the entire process and data, I found that only part of the process needs to be modified. The demand can be fulfilled, and in the end, it only takes one week of development, which is to earn 10 million in revenue for the company.

1. Cooperate with the product development department to plan products, and be responsible for the development of various language analyzers. In terms of work, improvement due to the unlimited recursive grammar defined by STIL, which caused the stack over flow of the C language, which made the company’s products unable to analyze this type of file and caused the loss of customers 2. Research and develop product development for Boundary Scan test with colleagues in the department.
