Exploring how great engineers and product leaders think, learn, and build

The Engineering Mind
The Engineering Mind explores how great engineers think, learn, and build. Each edition dives into new technologies, frameworks, and lessons from real-world engineering — not just the "how," but the "why" behind better systems and better decisions.

The Product Mind
The Product Mind is a newsletter about building things people actually use. I break down product thinking, discovery, GTM alignment, and how to turn ambiguous problems into clear, shippable decisions. Expect real stories from engineering → product collaboration, new tools/frameworks to try, and lessons from shipping in the real world.
