Rebuilding the software an entire dealer network quotes on
20 engineers at peak
The client sells every door through independent certified dealers. The software those dealers use to specify and price a door is the point at which the order book is either filled or lost — and it had been built on a framework generation that had been superseded.
We moved it onto current foundations without a break in the network’s ability to sell. That constraint shaped everything: no cutover weekend, no period where a dealer could not quote.
