2 YOE. 2 Year job gap. How to start again?

Hi, I worked as a backend python dev before vibe coding era. I worked for 2 years and during my work I had performance issues due to leaves that were due to two major surgeries. So, due to performance issues, I was asked to resign.

Currently I'm doing part time PhD, so I can do a job on the side. How do I approach this? How can I restart? I'm 27YO.
