Approximately 15 - 18 days work - must be able to commence no later than 12th September and work simultaneously with our team for at least half of their working hours (06:00 BST - 14:00 BST)

Apart from API-related work, you must have the skills to resolve issues with regard to the docker platform. We have two Dot Net applications, both applications are running on the docker platform. This issue will need resolving before starting any API work.

Frontend projects (React) connecting to Dot Net applications haven't been configured to manage development and production environments. There will be a need to streamline the deployment process of the frontend applications using GitLab CI/CD.
Also, all applications are hosted in the AWS environment, and we use the ECS platform to deploy and host them. So knowing the above platform is an added advantage.

We will share the Figma link to provide more detail to those who can fulfil the skill-sets.
