- Proven track record of moving outside of organizational boundaries to start new initiatives, prototype the path to production, and reorient the organization to support the new initiative.
- Experience working in fast-paced environments, whether at a start-up, in an incubator, or on a zero-to-one team inside a larger enterprise.
- Proven track record of leading large, ambiguous, org-spanning technical initiatives with significant business impact.

- Contributions to open source projects or the iOS community, or other external recognition of technical leadership.
