Three systems that had never talked to each other — storefront, manufacturing, accounting — now run through one integration layer and a custom operations dashboard. Build orders are being placed on its recommendations.
WMD manufactures modular synthesizers and guitar pedals. I work on both halves of the company: the firmware inside the products, and the systems that let a small hardware business see what it is actually doing.
On the systems side, three tools ran the company and none of them shared anything. I built the integration layer between them and an operations dashboard on top, which is where lead times, build planning and true assembly costs became visible for the first time.
On the firmware side, the Metron sequencer is a legacy codebase that was never version controlled — seven simultaneous state machines across several ten-thousand-line files. I refactored it into something modular, cleared three hundred compiler warnings, built a real release process with CI, and spent months tracking down SD card bugs that were losing customers' work. It is now becoming the hub of a CAN bus ecosystem for other modules.
