pkrr.io — a poker platform, on web and mobile.
Shared game state across devices, kept in sync by a realtime service
of its own.
The hard part is correctness under concurrency, when
a dropped connection has a cost.
clientbilling.com — invoicing that shows what getting paid costs.
Payment costs are applied to the invoice before you send it, and
every number has a source. The same invoice, under the same rules, for a
person or for an agent.
The hard part is staying out of the payment path
entirely, so we are never the merchant of record and never hold card
data.
donedone.io — a commitment manager, not a task manager.
Advisors that watch for scope creep and clarify what "done" means,
without taking the work over. No streaks, no scores.
The hard part is restraint: an assistant that helps
most by doing less than it could.
mssg.to — messaging links that just work.
A small utility that does one thing, fast, for anyone who needs to
hand someone a link to a conversation.
The hard part of a tool this small is that there is
nowhere to hide: it is correct and instant, or it is worthless.
