For the past 7 years I have been working in tech companies. I was able to significantly advance in my career during this time.
When I started my career I wasn't aware that I could negotiate my salary and was paid way below what I was worth. I was becoming a great employee with minor increases in salary.
After I started implementing the salary negotiation strategies and tactics that I now teach in my courses, I was able to more than triple my salary in just 2 years.
