Expertise in Extending "Black Box" Applications

A partner in the precision manufacturing sector relied on the Carveco application for their core operations. While powerful, the software had critical workflow gaps and no official API or developer documentation. They were forced to perform hours of repetitive manual tasks, creating a major bottleneck that limited their production capacity.

Our team performed a deep analysis of the application, reverse-engineering key components to understand its internal architecture. Using this knowledge, we engineered a suite of custom plugins that integrated directly into the Carveco environment. These plugins automated their entire workflow, operating seamlessly as if they were native features of the original software.
