Answer 1

Honestly, and personally; my most significant accomplishment is getting where I am today, and what I had to go through to get here!

When someone first learns to code, it is hard enough; but when even more practices arise, the learner needs to adapt to these, and learn how to apply them.

To do this, you must... PRACTICE!!!

This may not fully answer your question, but this is what I find as my most significant accomplishment in my career: getting to where I am today, and overcoming everything that has come my way to get here.
