BairesDev vs Data Science UA: overview
BairesDev
BairesDev was founded in Buenos Aires in 2009 and is now headquartered in San Francisco, with several thousand engineers across Latin America. It sells staff augmentation, dedicated teams and project delivery, and its AI practice covers ML, data engineering and generative AI. Its size means it can add many engineers quickly in U.S. time zones. AI is one practice inside a general software company, though, and its marketing volume is larger than the specialist evidence behind its AI work.
Data Science UA
Data Science UA began in 2016 as a data science conference in Kyiv, founded by Aleksandra Boguslavskaya, and grew into a recruiting, outstaffing and AI consulting business. Recruiting is a core line, and it says hiring averages two to four weeks. Its community of AI engineers in Ukraine and beyond, quoted at 10,000 to 30,000 depending on the source, gives it reach that general agencies lack. The screening is recruiter-led, though, so the technical depth of each shortlist depends on how well you brief them and on your own interviews.
