Technology is slowing growth
Architecture, technical debt and scaling problems can quietly become business constraints.
Independent judgement. Practical progress.
Senior technology leadership.
Without another full-time executive.
I help leadership teams solve complex technology, architecture and AI challenges and turn difficult decisions into a clear path forward.

A practical kind of seniority
Close enough to the detail.
Clear on the bigger picture.
Technology problems rarely begin as technology problems. They appear first as slower delivery, rising cost, unclear ownership or growing operational risk.
I connect what is happening in the architecture and engineering team with the decisions leadership needs to make. The aim is practical progress: simpler choices, clearer priorities and teams that can move forward.
