I have been working in the Crypto Currency domain for the last 4 years and have sound knowledge of coin, Ethereum, Polkadot blockchain along with Defi, and NFT knowledge. I am working on 3 parallel Defi and NFT projects in this domain one being creating a lending and borrowing platform by staking the top 10 ERC20, NFT, AltCoin. A very ambitious and promising project where we have a governance mechanism and also a separate token for voting rights. My specialization lies in C#, React, Angular and NodeJS, python, technologies, and I am also well versed with coding in Solidity and RUST. I have written intelligent contracts and can develop Security Tokens as well. Last but not least, we are also working on the blockchain-based replica of traditional debt collection applications. I am looking forward to working with you.
