Development Team

I have been working as a backend engineer from the scratch of this project. The time I joined the team, it contained 15+ people formed with the product owner, scrum master, AWS solution architect, cloud engineers, backend engineers, mobile app engineers, QA engineers, and UX/UI designers. After the successful release of the app until now, it has been growing with new features and rules continuously. The current development team contains 8 members including product owner, scrum master, backend engineer, mobile app engineer, QA engineer, UX/UI designer, and two operational executives.

Development Process

The team has been following Scrum from the very beginning of the product development. The team tends to start with a day-long sprint planning meeting to set the upcoming tasks and achieve the goal in the next two/three weeks. After a sprint is finalized, the development team starts to perform the assigned tasks. A daily scrum takes place at the beginning of the day for 5–10 minutes where all the members of the development team share what goal has been achieved in the previous day, what tasks are aimed for the current day and, what problems are being faced during the development. At the end of the sprint, a sprint review event occurs and after a successful sprint and release, the team celebrates it by throwing a little party.

Technology

The whole project has two main sections. One is the mobile app itself and another is the web admin portal to manage all the administrative operations for this app. The technologies used to develop the whole project are —

Mobile App

Web Admin Portal

Backend

Serverless architecture, AWS, NoSQL, Celery, Redis, Firebase.
