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
