There is no easy way to be a skilled person. You have to put the effort in order to earn the skill. Similarly, you won’t be fit for a position if you haven’t earned it yourself.
To become good at programming, you have to practice programming a lot. To handle performance issues, you need to know how to tackle them through experience and learning. There is no easy way around it. You can’t force a person who doesn’t understand programming to write software.
This is applicable to everything. Only with the experience you will be able to get the position that you need. And you will be able to perform only if you are qualified enough.
