API script to move tasks to board in Asana (Projekt Management Tool)

We are a startup in Berlin using Asana to organize our workload. Now we want to sort our tasks better. Therefor we are looking for a freelancer who can write us a script that moves tasks that are assigned to a specific team member to a specific board. In this board the team member can than freely organize his tasks (instead of just using the "my tasks" view) We already do have a script, it needs to be adapted to our use case. One way to adapt the script would be to add logic so that this script runs for every user on our team. Another option would be to get every project in the workspace and then every task in every project. Then run the same logic to add every task to the board. The simplest way to run the script would be with a cron job. Can you help us with that?
