Web3 Systems

Solidity and Web3 Product Engineering

I work on Web3 products where onchain logic changes how the system behaves and what users can trust. That includes escrow, token operations, smart accounts, settlement flows, and the offchain systems around them: APIs, operator tooling, audit trails, and execution workflows.

Hire on UpworkAbout me

What I handle

Contract architecture, business workflow mapping, and integration design.
Smart-account, wallet, auth, and lifecycle orchestration around the chain layer.
Foundry or Hardhat testing, deployment workflows, and operational runbooks.
Full-stack product surfaces for users, operators, and admin workflows.

What I usually build

  • Escrow and milestone release systems with disputes, refunds, and execution history.
  • Token launch and operations flows with progress visibility, retries, and recovery.
  • Deposit and approval workflows with operator review, auditability, and durable state tracking.

Milestone Escrow

Production-oriented foundation for a Base-native milestone escrow: smart-account onboarding, programmable milestone release, disputes, and compliance-aware workflows—engineered as a serious monorepo, not a wallet demo.

Questions clients usually ask before starting

Do you only write smart contracts, or can you build the full product?

The full product. Most serious Web3 systems fail at the edges between contracts, backend workflows, auth, operator tooling, and user-facing UX. I work across that boundary.

Can you help if the main challenge is product logic rather than pure contract complexity?

Yes. That is often the harder problem. I am usually mapping trust, approvals, settlement, and failure handling across both onchain and offchain systems.
