Seeking Solidity Developer to help produce 3 products for us on a semi-tight budget. We only need back end and smart contracts. We will need smart contracts for 4 tokens, 6 liquidity pools, and swap contracts to go between the 4 main tokens. There will be a few more items needed to be done, but at that time, more budget will be available to rehire. Please note the budget posted is strict for now on the items we need. Please do not place a bid if you plan to throw an offer back or request more money. We have equity to offer as well as an additional rehire later. For now, our budget for what we need is strict.

Hello! I'm experienced fullstack / blockchain developer. I've been developing several investors crypto wallets backend/blockchain part (here is presentation [login to view URL])) and project heavily connected with different crypto currencies (DataTrading (.net Core/C#, ReactJS, MsSQL), see my profile and portfolio for details). Now I've just finished a multi-level marketing project based on TRON network (it uses the same Solidity language): [login to view URL] with very complicated inner logic ([login to view URL]). I've implemented frontend (ReactJS), backend (NodeJS, PostgreSQL) and blockchain (Tron/Solidity) part for this project. Here is also my another not trivial Ethereum smart-contract with build-in jackpot lottery (the more you buy tokens the more chances to win in one-time lottery [login to view URL]).
