About this gig

I design and develop fully custom NFT marketplaces with full Web3 and blockchain integration built around your vision, not a recycled template. Every smart contract & line of code is written and tested specifically for your project, deployed first on testnet, then on mainnet when youre ready to go live.


WHAT I BUILD

  • NFT marketplaces: mint, list, buy, sell, bid, fixedprice & auctions
  • Custom minting flows: whitelist, presale, airdrops, IPFS/Arweave storage
  • Smart contracts: ERC721 / ERC1155 (or chain equivalent), royalties, fees
  • Token systems: utility/governance tokens, staking, rewards
  • Admin dashboard: manage collections, users, fees, content & ban controls
  • Web frontend: wallet connect, profiles, activity feeds, filters, search


CHAINS & TECH

  • Ethereum, Polygon, BSC, Solana and others (on request)
  • Web3 frontend (React/Next.js or similar) + secure backend/API where needed
  • Gasefficient, upgradefriendly contract patterns; full test coverage on testnet


PROCESS & RELIABILITY

  • Clear spec prototype/preview testnet launch mainnet deployment
  • You see a working version before final deliveryno surprises
  • Postdelivery support window for fixes and minor tweaks
  • NDA available

I build marketplace platforms from the ground up—custom vendor flows, split commissions, escrow logic, and role-based dashboards built around the exact business model, not plugin limits. I also develop custom NFT marketplaces with Web3 and blockchain integration, including wallet connections, smart contract interaction, and minting logic. When issues arise, I trace them to the source—fixing stuck withdrawals, commission errors, API conflicts, and database inconsistencies. I focus on clean architecture, stability, and long-term reliability.
