Sergey Royz
CML Team supported us with backend and blockchain development. They have quite a diverse expertise in technologies such as Java, Spring, web3j, and profound knowledge of the crypto industry. In the matter of weeks CML Team were able to build a POC microservice and then over the next month polish it to the perfection. This key microservice is already in production and allows us to scale even faster and win new markets.
