Every one of them runs in production today.

How I work

Talk to the developer

No project managers in between. You speak with the person who builds it.

Live in weeks

A usable prototype early, instead of months of specs. Then it grows with you.

Full stack

Data model, backend, interface and operations from one hand — hosting included.
