Working Theories
Where technology, engineering judgment, and company building are heading, and how to bet on it now.

Insights and Lessons Learned from the Field
208 pieces on the problems that actually reach a technology leader: what an architecture review should catch in the first hour, where engineering budgets quietly leak, which compliance work is worth automating, how AI changes who does what on a team, where the CTO role is heading, and why interoperability stalls for organizational rather than technical reasons.
This is the routine, tactical layer of the work, written to be used this week. The books are the longer-form strategic argument that sits on top of it.
Design Patterns
Patterns captured from building, running, fixing, and funding real companies, ready to apply on Monday.
Contrarian Briefs
The comfortable assumptions costing teams money, and what to do once you stop believing them.
Practitioner Journalist
What is actually shipping in tech, the CTO role, government modernization, medical devices, pharma, and health IT, reported by someone building it rather than covering it.

Native Alpha
Alpha, in investing, is the return you cannot explain by the market. Native Alpha is the operating version: the unusual advantage already sitting inside your company, your customers, your data, and your relationships, and the discipline of letting it decide what you build, buy, fund, sell, protect, and stop.

Native Alpha: Start With the Advantage You Already Have, Not the Opportunity You Just Noticed
Alpha, in investing, is the return you cannot explain by the market. Native Alpha is the business version: the unusual advantage already sitting inside your company, your customers, your data, and your relationships, and the discipline of letting it decide what you build, buy, fund, sell, and stop.

Test First, Discover Second, Build Third: A Practical Strategy for Brownfield and Legacy Software Engineering
For non-trivial changes to legacy systems, define the business outcome first, then how you will prove the change works, before you estimate or build it. Outcome, evaluation, bounded discovery, incremental implementation, in that order.

Alpha, Benchmarks, and Why I Borrowed the Word From Investors
Alpha in finance is the return you cannot explain by the market. Here is what that actually means, why investors bother separating skill from luck, and which parts of the idea carry over to running a company and which do not.

Capability Is Cheap Now. Advantage Is Not.
AI made building things dramatically cheaper, which quietly destroyed a lot of differentiation that was never real. How to tell commodity execution from differentiated execution, and where to spend the judgment you have left.

Someone Outside the Room Has to Care
Enthusiasm inside a company proves nothing. The strength of evidence for an advantage is measured by what somebody outside gave up to act on it, from a compliment at the bottom to a renewal at the top.

Product-Market Fit Does Not Tell You Who to Sell To
The same product can be ordinary for one buyer and transformative for another. Product-asymmetry fit and the Ideal Alpha Profile explain why the customer with the biggest problem is often the wrong customer.

Where Native Alpha Actually Lives, and How It Decays
Advantage is contextual, it hides at surprisingly small scales, it needs protection in the place it actually lives, and it expires. How to find it, where to put the fence, and when to admit it is gone.

First Principles Got Turned Into a Slogan
Reasoning from first principles means stripping a problem down to what you can verify and rebuilding from there. In executive hands it usually means ignoring people with experience. This is the real version, and how it fits with Native Alpha.

Why Email and Office Documents Are the Perfect UX for Starting Your AI Journey
It may sound legacy, but email and document-based workflows are the most effective user interface for launching real-world AI solutions. Here's why AI should start where customers already are.

When enough lessons point the same direction
Some problems keep coming back, so the pieces about them get pulled together and expanded into a single working guide. Two are underway: how an AI-native engineering organization is actually run, and how to make compliance and evidence something machines produce rather than people chase.

The AI-Native CTO
A Shahid Shah Fieldbook
AI does not make technical judgment cheaper. It makes judgment the scarce input, and it moves the technology executive from best engineer in the room to the person who orchestrates machines, teams, and customers toward outcomes.

Operational Truth
A Shahid Shah Fieldbook
Assurance built on human attestation produces documents, not security. The organizations that survive scrutiny are the ones whose systems can prove their own state continuously, by machine, without anyone being asked to vouch for it.
