After successfully completing the first phase of the project, where I independently implemented both the backend and frontend, I was entrusted with leading the subsequent phases. As the lead developer, I provided guidance throughout the development process and managed a team comprising frontend and backend developers to ensure project completion. Following the successful completion of the project, the company's corporate help desk team was noticeably relieved. Prior to the project, the team was responsible for creating courier delivery requests and was constantly overwhelmed with requests from the company's business customers.One of my other significant achievements was creating a CI/CD pipeline in GitLab from the ground up for a legacy ASP.NET MVC applications. This pipeline simplified testing and deployment, resulting in substantial time savings for the team during the development and deployment phases of the projects. Show less
