ARCHITECT /team lead

Senior Java Architect. Works with e-commerce, blockchain. Has 15+ years experience.

CTO. I have 15+ years practical experince and more than a dozen of engineering teams created from scratch for various clients of different sizes.
I enjoy designing elegant technical solutions to complex projects and learning new technologies. I like to solve complex problems and there is no difference for me is it connected with programming or with other part of our life.
I'm happy when my brain can work with full power. And it is important for me to reach a final goal, to bring my ideas to life and see that my solutions help and bring value.
My new area for development is blockchain.
