MobiDev vs Romexsoft: overview

MobiDev

Mobile apps with a real applied AI or computer vision component are what MobiDev actually specializes in building, out of R&D centers in Poland and Ukraine under a company incorporated in both the US and UK since 2009. Its case studies show genuine computer vision and mobile engineering work for startups and mid-size product companies, going well beyond generic app development. The dual-country R&D structure spreads delivery risk, but Ukraine here is a development location rather than the company's legal home.

Romexsoft

Cloud-native application development on AWS is where Romexsoft has built its actual engineering credibility, holding AWS Certified Consulting Partner status out of a company founded in Lviv in 2004, with representative offices in London and Chicago. That certification is a verifiable signal a buyer can check directly, unlike a plain marketing claim of cloud expertise. Two decades of operating history give the company a mature development process, though it doesn't have one single named industry vertical beyond its cloud specialization.
