Your projects:

• Write and test backend features in Python or Node.js under the guidance of a senior developer
• Refactor old modules when asked, keeping behaviour the same

• Debug failing builds in the GitHub Actions pipeline and note what caused them
• Fix bugs from the Jira backlog, starting with small, well-defined tickets
• Present a short demo of your work to the team every two weeks

What you get out of it:

• You will ship at least one feature that real users touch before the internship ends
• Writing tests is part of the job here, and you will get good at it
