Product Systems Engineer Open to remote roles

Clear on the surface.
Considered underneath.

I build native apps, interactive web experiences, and product systems. From the first decision to a release you can actually use.

Independent products. Real releases. A little curiosity.

How I work

The details
are the product.

01

Make the problem clear.

Reduce a complicated workflow to understandable decisions. LocalScan starts with one: turn a document photo into something useful.

02

Give the system good boundaries.

Keep interfaces, data, and operations coherent. PromptFlow puts evaluation and release decisions alongside the work they affect.

03

Follow through to the release.

Test the important paths, document the constraints, and verify what people actually receive. LocalScan and LocalView are available on the App Store.

Have a product problem worth solving?

Let’s make
something useful.

I’m open to remote product systems engineering roles worldwide.
