Solidity & React JS developer
$60.00/hr
I have over 3 years of experience as a Solidity and React.JS developer, 4 years of experience as a Software Engineer, over 10 years of experience in general programming and have Master's degree in Computer Science.
I can create multiple custom DEFI solutions and also fork existing ones. Blockchain development is a very complicated and sensitive business and you should choose to work with professionals that develop safe and tested smart contracts. Having an untested and poorly written smart contract can put your users funds in danger and ruin your entire project.
Some of the many projects which I've built in the past are:
• NFT launches/drops : regular, whitelisted, gasless whitelisting using wallet signatures, Merkle Tree etc.
• NFT staking, merging etc.
• ERC20 token ICOs: regular, whitelisted, gasless whitelisting
• ERC20 tokens with custom specifications: burnable, tax fee on buying/selling etc.
• DeFi forks of platforms (Uniswap, Pancakeswap and others)
• Creating a bridge for wrapping NFTs and ERC20 tokens between chains
• Custom smart contract solutions
I am highly capable of building you full custom solutions on Ethereum, Binance Smart Chain, Polygon and many other chains.
Other languages I have been coding over the years are: C++, C, Python, Javascript, DevPascal, Java, Kotlin, Rust, Matlab.
