As a developer, a Java program was developed to read IP addresses, IDs, and passwords from a CSV file, instead of connecting and executing commands individually on more than 20 Linux nodes via SSH. The program executes the appropriate commands based on the distribution (Red Hat or Ubuntu) and outputs the execution results as logs, significantly reducing task time.Another project involved building a C#.NET application to manage the warehouse of a company that manufactures parts for Toyota. This system enables recording, searching, and printing parts codes and quantities to manage inventory across multiple warehouses. The GUI functions as a form application, interfacing with SQL servers.TypeScript was also applied in a different project to design a chat tool capable of receiving and sending JSONP data.These experiences have made me skilled in all development stages, as well as designing, code development, and testing.
