We are building a Web3-powered platform that bridges digital ownership with real-world value. We are looking for a full stack developer with strong blockchain experience to join our team and help bring the MVP to life. This is a hands-on role where you will own the blockchain integration, smart contract development, and backend/frontend Web3 architecture.

What You'll Do

- Design, write, test, and deploy smart contracts for minting and payments
- Integrate Web3 functionality into the Next.js frontend (wallet connect, minting, downloads, payments)
- Build secure backend routes to handle metadata, file uploads, and on-chain/off-chain syncing
- Ensure smooth communication between the Express server, IPFS, and the blockchain
- Optimize for low transaction costs and user-friendly experiences

You Should Have

- 5+ years of full stack development experience
- Proven experience deploying production-grade smart contracts on an EVM-compatible chain
- Deep familiarity with the full Web3 stack (wagmi, viem, ethers.js, IPFS)
- Comfort with both frontend (React/Next) and backend (Node/Express) development
- Understanding of NFT standards, minting flows, and token transfers
- Experience with MongoDB or similar NoSQL databases
- Ability to work independently and take ownership of the blockchain layer

Nice to Have

- Background in education tech or marketplace platforms
- Familiarity with CI/CD and deployment pipelines
