I'm an expert at solidity and typescript and i have significant experience using hardhat and nextJS. I've worked on various Blockchain projects. Part of the Blockchain team at mousehaunt, i was able to developed in solidity, many smart contracts such as: Marketplace V1, V2 and V3 (Solidity, Typescript, Nextjs) - inspired on decentraland, using transparent proxy pattern. This smart contract allow the user to sell ERC20 and ERC721 mouse haunt boosters and mouse heros. Stashing (Solidity/NextJS) - a smart contract that allows a a player stash their mouse haunt tokens on for a range of days. With a given amount and period stashed, any user can get a On-chain Tier, that it's used in-game to get benefits. SwapNFT (Solidity/Typescript/NextJS) - I was able to develop this idea in my free time and bring to team. That feature allow players to trade mouse hero 1:1. paying different fees according to stashing tier. BUSD-On-Ramp - A smart contract that uses pancakeswap router to swap BUSD for MHT.
