Fractional CTO · Technical leadership
I work with companies where software has become critical to customers, operations, or growth, but technical complexity has outgrown the current ownership structure.
I take responsibility across architecture, infrastructure, engineering delivery, and production AI while the work continues moving toward customers.
Recognizing the situation
What I take responsibility for
Architecture, delivery, infrastructure, and people affect one another. I take responsibility across those boundaries.
Architecture, infrastructure, engineering investment, and business priorities stop moving independently.
The path from idea to production has clearer ownership, fewer avoidable handoffs, and visible constraints.
Reliability, security, cost, evaluation, observability, and failure handling have named owners, including the risks introduced by production AI.
Selected leadership experience
Datagran · CTO, 2020–2025
I led engineering and redesigned the development and release cycle, connecting architecture, infrastructure, and product delivery.
Outcome: Production bugs fell from approximately 300 to fewer than 10. Product NPS improved from negative scores to between 90 and 100.

I led the technical work on inventory forecasting, guiding the data science team from data collection through systematic model experiments to production.
Outcome: After deployment, the customer reported being on track to save $1 million annually.
Selected writing
A CTO is not just a CTO. Early-stage startups need builders, growing startups need architects, and larger companies need executives. Hiring for the wrong stage can cost you hundreds of thousands of dollars and push the company in the wrong direction.

The person behind the work
Clients have often brought me in for a narrow implementation problem. My responsibility expanded when the work exposed problems in architecture, infrastructure, delivery, machine learning, or technical ownership.
