I'm a proactive engineer,
- always looking for improvement points,
- and giving support to my colleagues,
- and after running out of tasks, I ask for new ones
- I do classes and code open-source in my free time
Furthermore, recommendation letters given from people inside the company are not usually written for employees in the firms I've worked for, because there's no value added for the company for employees leaving faster thanks to the recommendation letters from the managers...
How do I make it obvious on my resume the fact that I am proactive and ambitious? I've three years of professional experience, but I'm good at what I do.
The background of this is that three years doesn't seem a lot to some recruiters when searching for a software engineer.
