Senior software architect with 18+ years shipping production systems — now focused on Web3.

I build practical, well-architected blockchain-integrated applications: dApp frontends, wallet-based authentication (SIWE), token-gated and NFT-access pages, on-chain/off-chain dashboards, and clean smart-contract integration into React / Next.js products. My strength is not only writing code — it is designing the system around it: clear boundaries, documented APIs, reproducible Docker setups, tests, and handover docs a client can actually maintain.

Before Web3 I spent years engineering data-intensive and real-time systems: algorithmic-trading infrastructure (400+ indicators, 200+ EAs, sub-100ms signal distribution), high-throughput automation pipelines (1M+ pages/day), and multi-tenant platforms serving thousands of concurrent users at 99.95% uptime. That background maps directly onto Web3 problems — reading chain state reliably, indexing events, building analytics dashboards, and keeping a dApp fast under load.

How I work:
• Architecture-first — spec and design before implementation.
• AI-assisted delivery, but I own every decision and review every line.
• Milestone-based, documented, testnet-safe demos.
• Clear scope, no unlimited revisions, written acceptance criteria.

What I'm looking for:
Remote Web3 freelance / contract / bounty work — dApp frontends, wallet auth, token/NFT gating, contract integration, on-chain dashboards, and architecture reviews for small Web3 projects. Crypto-friendly (USDT / USDC / ETH / BTC); escrow preferred on direct deals.

One boundary, stated up front: I do not take custody of funds, handle private keys, or guarantee unaudited financial smart contracts. If your project needs exactly that, I will tell you honestly and point you to an audited specialist instead.
