My initial career experience began with Shougang Automation and Information Technology Company as an associate software engineer. Our mission is to provide solutions and a real-time system to steel-making industry. Our projects export data from Programmable Language Controllers and load them to MSSQL. With our Silverlight website or WPF application, clients can check the status of equipment and products. In the first year, I just take part in the development controllers. Then I take part in two projects, one is coking system and another is continuous casting system. In the front-end I draw the equipments' diagrams with Blender and develop the reports with Stimulsoft, clients can view and download reports from our website. In the backend, I developed the WCF service to load data from database with entity framework. Both of projects already in use in production line. In Shougang I learned how to program and release a solution, also learned how to write neat and tidy code.Half and two years later, I felt that the state company is too stable to improve my technical knowledge. I moved to Advent, a corporation in financial software. I was assigned to the Data Service team as a software engineer which in charge of exporting, transforming, and loading data from physical files to the database. The physical files are provided by custodian, they upload raw files to our server. Then a background service will load the files and coke them, the data finally will be loaded to the database. Most of our clients are banks located in Europe and America. They can subscribe to the notification on our websites when data is loaded to the database, the clients can view the data and charts from our websites. I am responsible for building the Restful API and UI. Our API is based on the Dot Net Core, our website with Angular and KendoUI. Some of the parts are referenced Electron and Dot Net Framework. In Advent, I learned much new technologies and how to collaborate with the international team.In 2018, I joined the SLB in Beijing, I developed the drilling platform with Angular and NestJS with team members as a senior frontend engineer.
