Fractional CTO / CAIO · Senior Break Glass
Hands-on doing.
Senior thinking.
When a technical opportunity is complex—or a project needs to get unstuck—I bring experienced leadership and practical engineering to move it forward. From AI and challenging algorithms to web applications, systems integration, and production deployment.
Talented. Trusted. Temporary

HOW I CAN HELP
The right level of help, at the right moment.
01 / HANDS-ON INTERVENTION
04
Senior Break Glass
For the project that's stuck, the difficult technical problem, or the product that needs to move from promising to working. I step in, diagnose, solve, build, and help your team get moving again.

02 / FRACTIONAL LEADERSHIP
Fractional CTO / CAIO
Experienced technology and AI leadership without a full-time executive commitment. Architecture, strategy, technical decisions, delivery planning, team guidance, and sound adoption of AI.
Lead · Architect · Guide
03 / FOCUSED DELIVERY
Prototype or Production
Turn a useful idea into a working prototype, MVP, or operational system. Short, deliberate builds using modern development and AI tools—with an eye toward maintainability and a clean handoff.

WHERE I GET INVOLVED
Complexity is where experience pays off
Not a catalog of generic development services. These are the kinds of problems where deep technical judgment and direct execution make a difference.
AI + Machine Learning
Custom models, NLP, agents, model evaluation, AI workflows, and integrating intelligence into real products.
The measure of success is not how much technology we add. It's whether it solves the problem and can keep working after I leave.
Hard Problem Solving
AI-Assisted Web Apps
Systems Integration
Complex algorithms, analytical logic, data problems, optimization, and proof-of-concept engineering.
Fast, modern “vibe-coded” prototypes—then review, hardening, security, testing, and deployment for real use.
Cloud services, APIs, backends, data flows, legacy interfaces, and getting disparate pieces to work together.

FOCUSED ENGAGEMENTS
I have fractional time. I make it count.
I work with a limited number of clients on defined challenges. Often that's a focused engagement of a few weeks to a few months—not a long-term consulting dependency.

Find the actual constraint
A focused conversation about the problem, the environment, what's been tried, and what a useful outcome looks like.
