I will build your web3 backend, dapp API, blockchain integration

ABOUT ME

Smart contracts handle ownership but most Web3 products need a backend that connects on-chain state to fast, relational, off-chain logic. That's the layer most developers struggle with. I specialise in it.

WHAT I CAN BUILD

• NFT and wallet ownership verification via RPC
• On-chain event indexing: listen to contract events via WebSockets, sync to DB in real time
• Signed backend transactions
• Hybrid architecture: chain for ownership truth, SQL for game state, progression, analytics
• NFT game backends
• Web3 e-commerce
• Merkle tree generation for whitelist-based mints or airdrops
• Blockchain data APIs: token holders, transaction history, on-chain analytics
• Bridge and cross-chain data integration
• Indexer services that keep your database in sync with contract state

And more
