Ink-on-bone engraving: an open envelope with a broken wax seal on the left, its handwritten letter dissolving into a drift of fine ink marks that reorganize into an indigo path of connected nodes, crossing a dense engraved lattice and converging on a single brighter node at the far right — a message dissolving into signal and finding its one recipient.

Get in touch

I'm open to work where customer understanding, technical depth, and product judgment belong together. I'm especially interested in AI products, developer tools, and complex software that needs to feel clear to the people using it.

I do my best work on problems that cross customer needs, code, and product decisions: software people need to understand and trust, rewrites that can't break what already works, and editors people have to love. Write me directly:
