My background is payments. I spent 10 years at Fiserv and Clover Network Inc., close enough to the rails to learn the distance between what a press release announces and what a system actually does. Major Matters applies that habit to the current shift: I read the architecture against the announcement and name what is still missing before any of it works at scale.

I think in frameworks. The named models below are how that shows up on the page: I would rather leave you a lens you can reuse than file one more take. The ideas arrive faster than the newsletter can run them, which is most of the reason the newsletter exists.

The analysis compounds through four named frameworks, each with a permanent reference page:

I publish near-daily. Most editions analyze one development in depth; the longer pieces map how the layers connect. Everything I write follows the standards on the methodology page: the source hierarchy and the citation and corrections rules.

If you want to know whether this publication is for you, read one framework page. If it earns your attention, subscribe. It is free.
