EthersJS

A library for interacting with the Ethereum blockchain and its ecosystem.

EthersJS is a complete Ethereum library and wallet implementation providing compact, intuitive interfaces for blockchain interaction.

It offers secure key management, contract abstractions, and utilities for transaction handling with broad provider support for different networks.

Experience:

Developed a WebGL EVM wallet connector for ZTX metaverse platform using EthersJS, enabling NFT trading within the 3D environment.

Created RareMint's NFT marketplace on Polygon using EthersJS for efficient smart contract interactions and token minting.

Built an EVM NFT data indexer for RareMint using Moralis streams, Node.js, and EthersJS for tracking ownership changes.

Led the architecture of Knowledge.io's Ethereum-based token system for their successful ICO, focusing on security and efficiency.

Implemented wallet functionality for multiple blockchain projects before Viem/Wagmi became available, using EthersJS as the core interface.

ZTX

ZTX is a web3 metaverse platform backed by Jump Crypto and ZEPETO (a subsidiary of Naver Z Corp with over 200M users). The platform enables creators to build, play, and earn through blockchain-based NFT trading. As a software consultant in the early stages of ZTX, I was responsible for developing the react app to host the metaverse and the WebGL/EVM wallet integration.

RareMint

RareMint digitizes authenticated real-world sports collectibles as NFTs on the Polygon network, offering fractional ownership and trading of high-value items. The platform partners with professional sports organizations to ensure authenticity. I led technical efforts at RareMint to enhance the NFT marketplace's performance and maintainability, including the integration with Polygon network for efficient NFT auctions.

Knowledge.io

Knowledge.io was one of the first blockchain platforms aimed at knowledge-sharing with a token-based reward system. The project successfully completed its ICO in 2018, raising funds to build a decentralized knowledge ecosystem that included partnerships with advertising networks to monetize user expertise. My role at Knowledge included leading the architecture of the Ethereum-based token and supporting systems for their successful ICO, and forming a skilled development team across three countries.
