You’re looking at this all wrong. Take these experiences and failures as part of your learning. Keep plodding forward and do better next time. If you get a pip so be it. Do the best you can and play the long game. If you have survived 8 months and you feel the passion for what you do you can survive 8 years. The devil is always in the details. Throughout my career I have learned more from my failures than my successes. I suggest you should also. Don’t doubt yourself. If you don’t have a learning disability you can learn anything. Just be a bit more careful about the deployments and that really should fall to a devops group. Jr means many things the least of them being your technical awareness. Business acumen, social and many others you are just learning. Change what you can and don’t try to change what you’ll can’t. Others have said (and I agree) sounds like your company needs some more robust production processes and documentation practices. In addition assigning you a mentor would also be good practice ideally someone at the lead level or higher. Additionally you mentioned your manager is no longer in the picture and that’s critical. Managers are also important in helping to guide you to your technical mentor. Don’t beat yourself up too much. Keep marching on.
