“To err is human, to really foul things up requires a computer” – William E. Vaughan (probably)

Managing complex distributed systems can be a challenge, when something breaks.  I have a special gift for tracking down and characterizing problems, and either fixing them or providing sufficient information to the development team that hey can fix them.  This skill set has been hugely valuable in nation-wide mobile data networks with ill-behaved applications, with hard-to-reproduce failure modes only seen in the field and never the lab, and in complex data processing systems like orbit determination and prediction.

Teams may need troubleshooting too.  I have encountered dysfunctional and under-performing teams and organizations and devised ways of reorganizing or tuning that greatly improved productivity and team morale.
