I lead software development teams, mentor developers and help career changers learn to write complex software. At the core of all these efforts is a simple goal: empowering developers and magnifying their capabilities. Sometimes that means changing processes to allow teams to move faster, deploy code with less friction and confidence. In my courses and programs, empowerment is making the abstract practical with lessons and challenges which mimic the experience of being a software developer. If you actually read this, thanks.
