S01The business
A team you cannot see
WhoWorksWhen is our own product, for agencies and founders who hire contractors in other timezones. It keeps everyone's real working hours on one board, converted into the reader's own day, with wage totals alongside. Pricing is flat per workspace, never per seat.
As described by whoworkswhen.com
What we built
- Shift scheduling
- Timezone conversion
- Team availability board
- Real-time updates
- Mobile access
Each line has a number. A frame further down that shows it carries the same one.
What it had to do
Show a team's hours in the viewer's timezone, with no arithmetic.
Handle real schedules: shifts, patterns and exceptions.
Put the week's cost next to the week's hours.
S02Design
A week you can read at a glance
The board is the product, so the interface is built around reading it: a week of shifts as coloured blocks, the timezone you are reading in always stated, and a dark mode for people who check it at night. Violet marks what is scheduled; everything else stays neutral.

S03Engineering
Timezones are the easy part
Converting a time is arithmetic. The work was in everything around it: shift patterns that repeat, exceptions that break them, a daily view with hours and wage totals, and a board that updates as schedules change. Sign-in runs on Kinde and billing on Stripe.

S04Infrastructure
Shipped where it loads fastest
It is served from Vercel at whoworkswhen.com, with pages rendered ahead of time wherever they can be — so the first screen arrives as a file, not as a wait on a server. A change gets there through a CI/CD pipeline with automated tests, by way of separate dev, UAT and production environments.

S05Growth
A SaaS model built on one price
We architected the SaaS model around a single decision: one flat subscription per workspace, never per seat, billed through Stripe. The product was then upgraded to an installable PWA, so the board sits on a phone's home screen like an app. The site says in its own words that the product is new and has no customers to quote yet, so its pages argue from the problem instead — and each carries structured data, so a search engine reads it as software with a price.
