01Enterprise blockchain & private networks
Design Hyperledger Fabric networks with participant identities, endorsement policies, and chaincode that reflects the business agreement. Connect permissioned records with operational systems without placing confidential data on a public ledger.
02Ethereum, EVM & Solidity
Build contract logic for controlled issuance, transfers, permissions, and asset lifecycles. Tokenization and NFT platforms include the application workflows around the token, with clearly defined administrative privileges and upgrade behavior.
03Cosmos SDK & protocol engineering
Develop application-specific modules and transaction flows with explicit state transitions and invariants. Scope protocol changes around the network’s consensus assumptions, integration boundaries, and deployment constraints.
04Wallets, APIs & Web3 backends
Connect wallets, signing flows, and contract interactions to Go or Node.js services. Handle confirmations, transaction failures, and reconciliation so user interfaces can explain what has actually happened.
05Explorers, indexing & integrations
Turn blockchain events into queryable PostgreSQL records and API responses. Design replay, reorganization handling, and Redis caching for explorers, operational tools, and cross-system blockchain integrations.
06Security engineering & infrastructure
Use smart contract tests, permission reviews, and adversarial scenarios to check intended behavior. Plan node infrastructure, monitoring, key management boundaries, and release controls; an independent audit is a separate engagement where required.
