Performing maintenance on company applications by adding new features, implementing clean code, and applying the DRY (Don't Repeat Yourself) principle for increased efficiency.

I have learned many things on RuangGuru, such as what Golang is and its data structures. I have also studied web application development, particularly backend development using Golang. I have learned to use the Gorm ORM, work with Postgre SQL as the database, utilize Gin as the web framework, and implement JWT for authentication. Additionally, I have studied the MVC architecture in Golang development. Moreover, I have also learned about deploying Golang applications using PASS.
