Blockchain Developer - Quick Learner - Strong Analytical skills

I just love tech and programming. Web 3.0 is the next step in evolution of the internet and it really fascinates me, so I started blockchain development.

I develop smart contracts using solidity and use Hardhat framework for testing/deployment etc. Before using Hardhat, I used brownie for blockchain development. Smart contract security is highly critical so I always keep security considerations in mind while writing a smart contract. I can use - OpenZeppelin libraries - Chainlink Data Feeds - Chainlink VRF - Chainlink Keepers The smart contracts that I have developed so far are: (many more will be added to my GitHub repo soon) - ERC-20 - ERC-721 (NFT) - Crowdfunding - Upgradeable smart contracts - DeFi stake DAPP - Time vault for ETH/ERC-20 - Lottery
