Independent by choice.
I work independently across product design and software engineering. I value clear ideas, restrained interfaces, and understandable products that make a real difference. Everything above was designed, built and is operated by me.
Product design & engineering
From idea to production.
Clear ideas
Focus over complexity.
Understandable products
For real people, in the real world.
Have something useful to build?
A product to ship, an existing one to audit, or just notes to compare. Write to me.
