Hi, I am a solidity smart contract developer, with 5 years of programming experience in C++ and python. I am very fluent with concepts like object-orientation, data structures, and algorithms. I have developed three commercial ERC20/ERC223 tokens that have successfully been deployed on the ethereum blockchain. I have written smart contracts for tokens, ICOs and escrows. Moreover, I am also a solidity auditor. I always perform diligent testing before deploying any code to the blockchain as I understand the repercussions very well. One distinguished token that I have developed is a reward paying token, (much like NEO) wherein users are rewarded in ETH to hold the token in their wallets. A major issue I had to resolve while working on this project was to tackle the problem of a user claiming rewards twice on the same tokens by transferring the tokens from one wallet to another. I hope I have been able to express myself crearly and I am looking forward to working with you.
