Let's connect.

I'd love to hear from you and discuss how I can help address the needs of your business.

How I can help your business.

Both virtually and in person — here's what I bring to the table.

Organization Management

CTO Services (interim or permanent), staff performance reviews, and talent evaluation. I conduct top-to-bottom reviews of struggling organizations to turn them around and build winning teams.

Software Consulting

Need a project done? For smaller projects I provide individual development services. For larger projects I'll spin up an in-house or outsourced vetted team to deliver on time.

Advisory Board

Experienced in Advisory Board and Board of Directors roles. I provide expertise in helping your business grow, scale, and navigate critical technology decisions.

Code Reviews

Regular code evaluations help prevent technical debt and unlock bottlenecks in delivery times and system performance. I identify the issues holding your team back.

Rapid AI Prototyping

Proof of concepts for investors or your board, including attending investor presentations. I help entrepreneurs go from zero to one in the shortest time possible.

Training & Mentoring

I coach development teams to become high performing — achieving better velocity and predictable output at lower cost through proven methodologies and hands-on guidance.

Featured in the press.

Podcasts, interviews, and documentaries.

Let's build something extraordinary together.

Whether you need a technology leader, a hands-on architect, or strategic guidance — I'm here to help you succeed.
