Hi, I have 1+ year of experience in working with smart contracts and system design. I have recently completed a few projects one of which was a token ICO and another was a merkle distribution system for airdropping coins w/ VIP management system. I have also worked on a yield distributor which gives out APY according to an exponential decay function. Another one of my project involves implementing a snipe bot along with bloxroute BDN to speed up changes to finding rug pull. Do drop me a message so that we can assess what all is needed and work on getting it done as quickly as possible.
