Integra Sources vs Sirin Software: 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.
Sirin Software
Sirin Software is registered in Florida, but its engineering happens at R&D offices in Kyiv and Ivano-Frankivsk. The company dates from 2014 and focuses on embedded Linux, firmware and IoT device software, with directory headcount estimates between roughly 25 and 50. Clutch reviews describe board bring-up, driver development and IoT gateway projects for US and European hardware companies. For buyers who want a US contracting entity and Ukrainian engineering rates, it is one of the more direct options here.
