  • NAVIA YEDAPALLYI BHEEMAN
    Blockchain Engineer
    Chaintope Malaysia
    I’m a passionate programmer and a blockchain newbie from India. At Chaintope Malaysia I hope to create solutions in blockchain to the difficult questions in software design that are otherwise bypassed for lack of technology. Like all blockchain developers, I am intrigued by bitcoin and Ethereum and the calibre of cryptography they unveil. Since learning to write my first C programme, I have been fortunate enough to work on a variety of enterprise projects across domains like backup, telecom and security. Whether using c++ or python or sql the backend and dedicated servers had been my territory until not.
