Smart Contract Developer

If you’ve spent enough time in crypto, you know that even top auditors may fail to find critical mistakes. That’s why smart contract should be well developed in the first place. My priority is developing the most efficient and reliable solution possible in the shortest terms. Striving for efficiency is what drives me. I’m always in search of better solutions and better approaches. Not only do I care about efficient code, but also about the final goals and efficient ways to achieve them. I always care about future of the project I’m working on. I am able to admit my own mistakes and positively perceive feedback.

"Have had problems with other 3D modellers in this community, but Vadym is for real. He is now our go-to-guy for any 3D modelling and some other design stuff. Always delivers promptly with impeccable quality and at reasonable pricing. And he's also very pleasant to deal with."

"Vadym delivered very good work on this STL project and I enjoyed working with him. His communication was very responsive, and his skills strong. At one point when i was discussing the project with a client about what we wanted to improve Vadym had already made the changes before i even asked showing me just he understood what we where hoping to achieve. He was very cooperative with any amendments on this project. I enjoyed working with Vadym and will likely have additional jobs for him in the future."
