I was only seventeen back then and I was a Java Developer Intern, not knowing much about enterprise oriented coding.

The project leader in our dev team saw a lot of potential and passion in my work, but was convinced I wasn't taught enough to do the right thing.

I was mainly doing shitty mappers and services back then, which were somewhat used but never lasted long and were ditched a few months later, which always bummed me out. I wanted to make an impact on REAL projects that would deploy into production.

So Mister Mentor (GDPR forbid to use the actual name), who was always first to come and last to leave the office, taught me what it means to code for real.

We stayed after 5pm until 7-8pm multiple times a week and he taught me in a deeply understanding and calm way how to:
- Git (SVN)
- Refactor
- SOA
- Annotate
- Deploy
- Unit Test

And most importantly:
- How to debug like an absolute BOSS
(We even debugged native Java Libraries just for fun to see if we could break them)

Fast-forward a month later and little intern me made his first commit on production.

Without Mister Mentor, I wouldn't be half as good of a developer as I am today.
