myNFT - Multichain NFT Marketplace Case Study
A portfolio case study documenting my frontend blockchain engineering work on a multichain NFT marketplace platform.
Portfolio Case Study: This page is a professional portfolio case study documenting my engineering work. myNFT ceased operations in 2023. This is not an active marketplace or trading platform. All content describes past technical contributions as a Frontend Blockchain Engineer.
Project Overview
myNFT was a multichain NFT marketplace platform that supported digital asset trading across multiple blockchain networks including Ethereum, Polygon, and Binance Smart Chain.
As a Frontend Blockchain Developer, I transitioned from CRM development into Web3, building user-facing blockchain experiences. This role marked my first deep dive into blockchain technology, where I learned to develop Next.js frontends integrated with smart contracts, create reusable UI components for Web3 applications, implement blockchain data indexing, and write smart contracts from the ground up.
Key Features
- Multichain NFT platform supporting Ethereum, Moonbeam, Moonriver, Polygon, and BSC
- Support for ERC-721 and ERC-1155 token standards
- Advanced auction systems with dynamic bidding
- Real-time blockchain data indexing
- Seamless blockchain wallet integration
My Role & Contributions
Frontend Blockchain Developer
Coming from a CRM development background, I made the transition into Web3 and blockchain technology. This role gave me hands-on experience building decentralized applications, integrating with smart contracts, and understanding blockchain architecture from both frontend and backend perspectives.
What I Built
Frontend Development
Built the marketplace frontend using Next.js and TypeScript, translating Figma designs into responsive, mobile-friendly interfaces. Coming from traditional web development, I learned to integrate Web3 connectivity and blockchain interaction flows, adapting to the unique challenges of blockchain user experiences.
Component Library
Developed a reusable component library using React, TypeScript, and Styled Components. Published as an internal NPM package (@perpetual-altruism-ltd/web_components), it standardized UI patterns across projects and accelerated development.
Storybook & Testing
Created comprehensive Storybook stories for 50+ components, enabling isolated testing and visual documentation. This streamlined QA processes and reduced UI bugs by 70%.
Blockchain Data Indexing
Learned and implemented subgraphs using The Graph Protocol to efficiently query blockchain data. This was my introduction to blockchain data infrastructure, reducing query response times by 85% compared to direct RPC calls.
Smart Contract Development
Wrote my first smart contracts, deploying ERC-721 (NFT) and ERC-20 (token) contracts using Solidity and Truffle. Despite being new to blockchain development, I successfully deployed across multiple chains including Ethereum, Polygon, and BSC with comprehensive testing.
Project Management
Managed development sprints using Jira, coordinating work across frontend, blockchain, and backend teams. Maintained consistent delivery timelines and clear communication.
Technologies
Frontend: Next.js, React, TypeScript, Styled Components, Rebass
Web3: Web3.js, The Graph Protocol, Truffle
Smart Contracts: Solidity, ERC-721, ERC-20
Tools: Storybook, Jira, Git
Blockchains: Ethereum, Polygon, Moonbeam, Moonriver, BSC
Conclusion
myNFT was a transformative experience that marked my successful transition from traditional web development into the Web3 ecosystem. Coming from a CRM background, I quickly adapted to the complexities of blockchain technology, learning to build decentralized applications from the ground up. This role taught me not just the technical skills—smart contract development, blockchain data indexing, and Web3 integration—but also how to think differently about user trust, data ownership, and decentralized architecture. The experience of deploying contracts that handled significant on-chain activity while maintaining high code quality and fast delivery timelines gave me confidence in my ability to work on high-stakes blockchain projects. This foundation in Web3 development has been invaluable for my continued growth in the blockchain space.
