The Challenge
The system functioned but had fundamental architectural and hardware limitations that were constraining its performance ceiling. All three needed to be addressed for the product to reach its potential.The blowout problem wasn’t a single failure — it was four separate vulnerabilities that combined into significant capital risk every week
The I2C communication protocol was too slow for the data acquisition demands of the system. Sensor readings were lagging, limiting the precision and responsiveness of the device.
The existing setup-and-loop architecture could only execute tasks sequentially. Critical processes had to wait in queue — there was no mechanism for concurrent execution.
The board carried unnecessary components that added footprint, complexity, and potential failure points — including a multiplexer that the right protocol choice would eliminate entirely.
The custom-designed airbags required a 10A heating element — a power demand that the existing circuit couldn't meet and that had no designed solution in place.
The numbers tell part of the story. The real result is that a trading operation that used to carry significant overnight risk now runs with near-complete confidence — every night, without intervention.
