  1. Scalable and reliable Software development
  2. deep dive into machine learning
  3. advanced skills in programming languages such as Python, Scala and Spark

Is there anything from the Master’s program that evokes especially strong memories?

I am very glad that I took machine learning course offered by Annalisa Marsico.

I am still very disappointed that out of 13 modules from the elective area only 5-6 were offered during my masters time, what did not provide the specialisation I wanted.
