Derrek Bertrand

Engineering Manager / Software Engineer

portrait image of an extremely suave and handsome man

I am an engineering manager who specializes in continuous improvement and outcome driven teams. Teams are at their best when they are constantly striving towards greater outcomes.

I am a software engineer who specializes in legacy displacement, high impact migrations, and always-on systems. I am at my best when there is no good time for downtime and 3AM failures are a non-option.
