Developed a stateless verification service allowing citizens, banks, and courts to validate documents via hash comparison, returning cryptographic proofs (Merkle + on-chain anchors) with deterministic VALID/INVALID outcomes. Implemented fine-grained access control and governance mechanisms, including multi-organization endorsement policies, court-ordered record freezing (legal hold), and role-based authorization via Fabric MSP, ensuring compliance with real-world administrative hierarchies. Leveraged Private Data Collections and off-chain storage patterns to separate sensitive metadata from public state, achieving data privacy, regulatory compliance, and optimized ledger size. Designed the system for scalability and fault tolerance, utilizing Fabric's modular architecture (peers, ordering service with RAFT) and asynchronous anchoring to public chains to maintain high throughput and resilience under load.

Designed a hybrid trust architecture combining Hyperledger Fabric (private ledger for core transactions) with Polygon anchoring (via Solidity) using Merkle batching for public verifiability, auditability, and cost- efficient scaling. Built high-performance Golang microservices orchestrating Fabric and public blockchain interactions (hashing, batching, anchoring, reconciliation), ensuring eventual consistency across distributed ledgers. Implemented resilient, idempotent workflows with asynchronous processing, event-driven architecture (Fabric events), and retry mechanisms to achieve fault tolerance and high reliability in a multi-organization environment. Developed a stateless verification layer with QR-based validation, enabling trustless verification of e-BL and credentials via public blockchain proofs, eliminating intermediaries and improving transparency. transparency.
