What we have built.

Delivered projects and representative builds. Each one is a full technical account: the problem, the architecture, the non-obvious decisions, the numbers.

Cards marked Scenario describe how we would build the system, based on our experience with similar work — the architecture is real, the metrics are a reference point rather than a delivered result. Cards without the mark are delivered work.

B2B · Wholesale distribution · electrical goods · 8,000 SKUs Scenario

Integrating a website and marketplaces with the accounting system for a distributor

Daily spreadsheet exports replaced with a stable exchange over the accounting system's HTTP services and a message queue: stock and prices synchronise with the website and the marketplaces close to real time, marketplace orders post automatically, oversells down to near zero. The accounting system stayed on-premise with no external IP.
