Integra Sources vs Developex: overview
Integra Sources
Two hardware and software engineers set up Integra Sources in 2014, and it now operates from Astana, Kazakhstan with a team in the low dozens. Its service list covers electronics design, embedded firmware, Linux kernel and driver development, computer vision and robotics, and it has collected a long run of Clutch reviews for IoT and device projects. Rates are below those of the European and US firms on this list. Buyers get engineers comfortable at the register level, though with less of the process documentation that regulated industries expect.
Developex
Developex has written software for hardware companies since 2001, and its client list leans toward consumer electronics and peripheral makers who need firmware, drivers and the desktop or mobile utilities that configure their devices. The company is based in Kyiv with offices listed in Munich, Kraków and Zagreb, and directory estimates put the team at about 250 to 350 people. A company blog post put its embedded group at more than 30 developers (per company website; independently unverifiable). That makes firmware a real practice inside a larger custom-software business.
