VTPLFull Stack Developer
Jan. 2023 - Aug. 2023Seoul, South KoreaI worked as a Fullstack developer in VTPL, a company manufactures, sells, and exports cosmetics. The main objective was developing a web application that the MDs and the managers of VTPL use to manage inventory, product information and automated their tasks. I extracted structured data from external sources such as inventory management firms that store and deliver VTPL's products in schedule. Because our project was written in Javascript, I used cron scheduler library to set tasks scheduled, leaved text file logs about the API requests and responds, and set slack bot to send message if there was any failed requests or a weird dataset was downloaded. The destination of data was just normal database. Our team called the storage as just "database" because VTPL did not have an experienced developer and data engineers, and I was not familiar with data engineer by the time, but regarding its characteristics, it was close to the data warehouse. The saved data were cleansed by the rules that I set, and transformed into adequate formats to be rendered in the tables in the frontend components that I developed. After the service was released, the managers requested for the data visualization and excel exporting functions, so I added a frontend functions that can visualize the data in plots, and select and export the selected categories' data in excel file. Other than the web application development, I gathered the requests of the managers(the main clients of the service), created drafts for frontend components in Figma, managed task schedules of our team in all projects because we suffered from the absence of the team managing skills.
