Engineered for
high-value systems

End-to-end backend development across four specialized domains - each built for production scale from day one.

001

Blockchain & Wallet Infrastructure

Full-stack blockchain middleware from node integration to multi-chain wallet systems. Reliable deposit/withdrawal flows engineered for exchange-grade uptime and operational accountability.

Production systems, shown in context.

Eight case studies across custody, signing, contracts, quant research, machine learning, execution, and mining operations.

001

Multi-Chain Wallet Service

Custodial wallet service for multi-chain deposits, pooled wallets, and outgoing transfers, built with stable APIs and layered signing controls.

  • Incremental blockchain indexing for reliable deposit detection.
  • Custodial wallet pooling with sharded wallet generation through MPC.
  • Multi-party signing for withdrawals with validation before broadcast.
  • Stable wallet interfaces such as balance, address creation, deposit listing, address validation, and transfer.
  • Adapter model that can support more than ten protocol integrations without changing upstream callers.

Architecture

readswritesapprovedindexed stateCustomer requestThe user or customer interacts with the custodial service, not directly with wallet internals.Custodial serverThe server owns product-facing requests and calls stable wallet interfaces.Wallet serviceA durable Go service routes balance, address, deposit, and transfer operations.Chain adapter layerProtocol adapters normalize chain-specific indexing, address rules, fees, and broadcast behavior.ValidationserviceTransfer requests pass business, risk, and security checks before any signature is released.Signing service (MPC)Multi-party signing and MPC-backed shards produce a signed transaction without weakening custody controls.Blockchain broadcastThe wallet broadcasts signed transactions and indexes final chain state back into custody records.
