My skill at troubleshooting has caused me to be the goto guy in every project, which lends great credibility and opportunities for leadership. Your pride in your troubleshooting skills isn't pride in a side-quest, it's pride in having a deep understanding of how systems work in general and in the specific.

"Good troubleshooter" might not look great on a CV, but all of your coworkers naming you as the most valuable member of the team, and a natural leader, is worth more than any feature launches.
