Task management Startup

We were commissioned by a startup to create a task management platform. The platform include 3 main actors, client(create new task on the platform), assistant(work on tasks created by client) and admin(manages clients and assistant). We started by creating low fidelity design and iterating with the client until the workflow was acceptable. We agreed the development cycle would be completed in 12 weeks with weekly checkins. On the 13th week we deployed the system to a handful of users. We discovered some defects that we quickly fixed. Once the client was happy with the product, we handed over the system to the client's development team. This included documentation, github repositories, infrastructure code and a presentation detailing all key decision made.
