Financial aspect
The number of Ruby engineers is falling now, and they are highly in demand today. But, unfortunately, because of this, engineers' services prices are rising, and in the USA and Western Europe, they're the highest. For example, as the data shows - an average salary of a RoR developer in the USA is around $127K. In the UK - it's around £55K which is equal to $76K. So, finding experienced RoR developers could be costly and time-consuming. So then, companies prefer outsourcing web development to Ukraine. The IT market is growing in Ukraine and offers a wide range of services at attractive prices.
