Experience
Red Mart
I worked on this project as a senior web developer and led a team of eleven. We built this website using Ruby on Rails and React. I also hosted PostgreSQL on a Nginx server, introduced the agile methodology for product management, and utilized UML to design the process and database structure. I also wrote perfect test cases for payment.

I began developing the front-end using the Create React app, which is provided by Facebook, and then later adopted Redux, Redux-saga, React Router, Axios, and more. This website was built using Python/Django and React. I also used the Django REST framework to create RESTful APIS and Django REST Framework JWT to implement token-based authentication.
