What people who have worked with me say

These quotes are from engineering and product work, not invented sales reviews. The sales practice uses the same habit: find the hard problem and stay with it until it moves.

I brought John Sambrook onto a risky and highly political project that had far-reaching consequences within our company. John found solutions to difficult problems, problems I could not have solved without him, thwarting doom over and over again. He produced documentation and code at a professional level I have rarely seen elsewhere in my thirty years of software engineering.
