A day is enjoyable when all pieces of the puzzle fall into place and you have written something that really works.

A day is less enjoyable when you have been busy solving a problem for a long time and you don’t succeed or you have done something wrong and have to start again.

Firsthand experience

External data is also used. This data is frequently collected from an external website and processed for the client. It often happens that these websites have been modified so that data can no longer be collected. How do you solve this?

You take the log files and go through these until you have found the cause. You also go to the client’s website and see if something has changed. When you discover where it goes wrong, you investigate how you can rewrite your code so that the systems are compatible again. It is important to solve this directly. Your other work is then put aside. When you have solved it, you check if the systems work well together and you can retrieve the data from the system again.


As a Back-End Developer at the Matrixian Group you can develop yourself in different ways. You can become a Team Leader, but you can also become specialised in something. You can follow relevant training course for this. At the same time, you can work on your personal growth by following training courses.
