I have worked here for 2 years.

I have a lot of feelings about it.

I feel sad because my coworkersI will be miss, because w my coworkers. We spent a lot of enjoyable times during theour lunach timebreaks.

But i, I also feel happy because iI had a lot of conflicts with the technical leader.

We did'n't agree with himon a lot of things.

1. "didn't" is a contraction of "did not", so the apostrophe (') should be replacing the "o".
2. This could also be written as "I didn't agree with him on a lot of things."

My point of view is that code should be clean and nice code, while his is "enoguh work it ispoint of view is that code should be "good enough".

This is my best guess at what you intended to write.

So, this situation created a lot of conflict.

I hope at the next job will be more techinicialer leader.

The misspelling of "technical" aside, I am not quite sure about what you wanted to write here.

"we" or "I"? Did you not agree with him or you AND your coworkers didn't agree with him?

My point of view is that we should have clean and nice code while his is "enoguh work it isit's good enough".

I hope that at the next job there will be a more techinicialer leader.
