Welcome to the community.
If you are asking for broad view of the data science career path you can try this:
But, if you are asking for a roadmap regards the deeplearning.ai platform, i would follow this path:
Introductory
- Mathematics for Machine Learning and Data Science Specialization
- Machine Learning Specialization
Intermediate
- Deep Learning Specialization
- Tensor Flow: Data And Deployment Specialization
- Tensor Flow: Advanced Techniques Specialization
Advanced
- Machine Learning Engineer Specialization
- Practical Data Science Specialization.
Keep in mind that these are just suggestions. The best roadmap it will depend of your goals.
I hope this help
Best regards
