Independent technical advisory

Chief Architect &
Technical Advisor

I work with CTOs and engineering leaders on architecture, AI adoption, and the delivery decisions that follow. I help connect what the business needs to what the systems and teams can actually support.

Where I can help

When the next decision
needs a closer look.

Will this approach hold up?

A proposed architecture, a vendor promise, or a growing platform. I work through the implementation, dependencies, and operating constraints with your team so you can decide what to keep, what to change, and what needs testing.

How do we make AI useful here?

We look at the work you need to get done, then work through where models and agents fit. That includes the data they can use, the actions they can take, how the harness is built, and how you'll know the result is reliable.

What is getting in the team's way?

Delivery problems often cross the boundaries on the org chart. I help trace them through the systems, team responsibilities, and review process, then work with your leads on changes they can carry into everyday engineering.

Working together

An ongoing technical partner.

Someone who knows the context, can challenge a proposal, and stays involved as the work moves forward.

I work alongside you and your engineering leads, getting close enough to the systems to give useful advice. We can move from a business question to a design review, into the code, and back to the decision you need to make.

We agree on the scope and a working cadence that fits your team. That can include reviewing designs and partner work, working through difficult decisions, and helping engineers build the judgment to carry the changes forward.

A focused place to start

A review of a proposed approach, a working session on a difficult system, or training built around your team's actual work. We define a useful outcome and the work needed to get there.

More about me

AI

I've built AI platforms and internal agents that teams use in everyday work, including mapping system dependencies and preparing code changes for review. Getting a return means choosing useful problems and accounting for the integration, evaluation, and operating costs. I bring the engineering and business judgment to work through both.

Transformation

My career has included transformations at progressively larger scales, from a client platform to an engineering organization to an enterprise. That work connects business priorities, system architecture, and the sequence of changes teams can carry out while the business keeps running. I've worked through those decisions with executives and implemented the changes alongside engineers.

Leadership & delivery

I've led engineering teams, developed managers and technical leads, and restored delivery reliability. That experience also shapes how I use coding agents: clear responsibilities, bounded work, and review that checks what was actually built. The aim is to help engineers manage more work while retaining the judgment and accountability needed to ship it.

Public work

I build inference engines, model investigation tools, and GPU performance experiments to work through questions I want to understand. I publish the code, measurements, and reasoning, including approaches that didn't hold up. You can inspect the work and follow how I arrived at a conclusion.
