Data engineer..need your help

I need your help. Hi I feel like I am stuck in TCS. It has been 6 years and I want to change my life. I want to earn good and give my parents what they deserve. But this salary is not enough. Out of 6 years , have 4 years in a support role in SAP. And 2 years as a power bi developer. I got into a project as a data engineer, i thought I would learn but this project is more focused on the testing part. So what is self learnt this year is 1)I databricks following udemy 28 Hours videos 2)I learned sparks from one Paid course which my friend purchased. 3) I learned about the Azure data factory from udemy. 4) I am good in SQL query and good in Python. I know in this project I won't get any development role and I really want to switch but how should I do? With this self knowledge can I put paper, i have self doubt.? Help me please
