Stablecoin Payment & Settlement Infrastructure
Designed a production-oriented digital asset payment infrastructure for businesses integrating stablecoin payments and blockchain settlement. The architecture covers payment orchestration, wallet interactions, transaction monitoring, settlement workflows, reconciliation and compliance-ready integration points. Digital Ownership & On-Chain Asset Infrastructure
Built a Web3 digital asset platform for minting, storing and managing blockchain-based ownership records.
The architecture combines Solidity smart contracts, NFT minting, IPFS metadata storage, wallet integration and a Web3 application layer. The system was designed to separate on-chain ownership logic from off-chain metadata while keeping the user experience simple and auditable.
Key components include asset minting, metadata management, wallet connectivity, contract interaction and testnet deployment. Aegis Web3 Architecture
