I don’t think that you can find programmers on Google, they don’t develop applications for clients, maybe they have a separate server where Google specialists work, I don’t know, but I know that without Google you can find a good company - which deals specifically with creating applications and interface. Soon I will need such a company.
there is quite a lot of competition in this area now, so you need to spend a lot of time to choose the best ones .. for example, you can look here: https://unicsoft.com/blockchain-development-services/
Specialists in working with blockchain technology are not difficult to find. Now this topic is actively developing and attracts high-class professionals in the field of programming. Prepare to make significant financial injections into this business. It should pay off well in the future and generate a lot of revenue.
Blockchain technology is a great fit for fast and secure data transfer. It is widely used in many areas. More and more countries are beginning to perceive cryptocurrencies and other things as quite equal to ordinary money. I also wanted to note the excellent service https://rpcfast.com/ that will help you use cryptocurrency for payments. And not only that, there are many interesting features widely represented.
