Software designer and Bitcoin expert.
With rich background in web design, managing high load systems and end-user application design, I am standing on the intersection of UX and strong cryptosystems. To make smart schemes and protocols actually work, they need to be designed from the ground up with the user interface in mind.
I consult individuals and companies on how Bitcoin and cryptography work, help them develop secure and efficient systems and user interfaces.
