Expert project management

On a web project, there's not only code. Working with Blackswan, you will have a dedicated project manager, available from 9am to 6pm by email, on Slack or Whatsapp.

He or she will be responsible of the detailed specifications in order to scope your requests and make sure we deliver them on time. Once validated, each task will be assigned to a developer in our planning and you can check easily when one task or the other will be done and when your project is delivered.

You will be able to go through all your pending questions during a weekly touch base, while arbitrating your priorities and reviewing your requests.

Hence, all is clearly scoped and you can relax
