Collectibles trade on condition, and condition is a grade. A marketplace that ignores it is a photo gallery with prices attached; one that respects it has to carry grade through search, listing, valuation and settlement without the collector having to think about it.
We built the consumer side — filtered browsing by grade, year and price, a portfolio that marks holdings to market, and the agent tooling that lets a dealer work on behalf of a buyer.
Marketplace, the listing page, and the portfolio behind them.
Discovery before specification
Before a feature was specced we watched people do the job it replaces. The spec usually changes after that, and it is cheaper to change it then.
A shared channel, not an account manager
The client had a channel with the engineers writing the code, and a standing invitation to the morning standup.
Something on staging every week
Work was judged by using it rather than by reading a percentage. Two-week plans, re-planned on Fridays, so a wrong assumption cost a sprint instead of a quarter.
Reviewed, tested, handed over
Every change was read by a second engineer before it merged. Tests, a README and a recorded walkthrough came with the handover.
