Personal and Professional Growth

Some machine learning projects, nothing too significant, just to keep my knowledge up-to-date on these field.
I'm working up on mastering my programming foundation via taking courses through coursera or challenging my self via website like hackerrank...

Read papers, news, talking with friends from other companies, following some celebrity (in data science field), LinkedIn to get updated on their latest revision on something.

Where do you see yourself in the future?

I'd like to transition gradually into machine learning engineer and be more proficient in my German skills.

Tips for beginners

How do you start programming and what should you start with?

Take an introduction course on any language you may like and find a project to do. If you have no motivation, just find a thesis or project in your school/university where you are forced to complete it or get expelled.
I do not recommend to read too many books before you get some real experiences on the language. Reading comes after you got enough trials and errors so that you will know what should you focus and avoid reading too widely on something unncessary or you do not need for now.

Which skills are required for your work?

Teamwork. Believe me or not, learning how to work on a team, how to use Git on colaborated projects and learn when should you seek for advises from seniors colleagues is more important than any technical skills you may have.

In your opinion, what kind of education helps to be good at your DevJob?

This is just a personal idea. I think I need to attend more seminar or courses on a platforms I'm using to get to know more of the use cases. Talking with experienced people, learning from their mistakes, and read books (but again, should just focus on what are needed at that moment).
