Oleksandr Yaskulskyi Senior Blockchain Developer E +1 - -  Khmelnytskyi, Khmelnytska, Ukraine SUMMARY I have been working as a developer for over 7+ years and have gained a lot of experience during that time. I am well versed in a number of programming languages. But I think it is not important how many languages I know. Still I am always eager to learn a new and make my skill sharper whenever I get any chance. "Quality over Quantity", this is my motto on developing. I am an individual but I have some highly skilled dev-colleagues, so I can provide quick and top-quality work with them if you need.
