Senior engineer shipping production software since 2009, the last 8 years building and hardening Web3 protocols. Contract systems I architected were taken through independent audits by STATEMIND (the firm that audits Lido, Curve and Yearn), QuillAudits and storming0x. I also build AI systems: agents, MCP servers, and LLM-powered security products, live today on the Chrome Web Store and the web.
Independent contract engineering for US clients. Web3 security and architecture: the DEGA audited contracts above, game worlds operated by autonomous AI agents, a medical claim system on the Midnight blockchain (Compact, pre-mainnet through mainnet), RWA tokenization with Firepan, and MCP agent tooling that lets AI agents hold wallets and transact.
Quality-focused engineering for a US-based regulated medical-device product: requirement and test-case reviews, defect triage, requirements traceability, release readiness in a distributed team.
Solidity contract architecture, cryptographic primitive design, dApp integration (viem/ethers), audit preparation, and testing infrastructure for Web3 products.
Full-stack TypeScript, Node.js, .NET and distributed systems for US enterprise clients.
React and TypeScript architecture for financial services, healthcare and SaaS clients, including Xtiva and SEON (Safe Fleet).
eFIN DEX for TokenPay: non-custodial exchange with atomic swaps (BTC/LTC/ETH) routed over Tor. Wallet UX, smart-contract integration, cryptographic primitives. First Web3 role.
Full-stack, .NET and SharePoint engineering for Wells Fargo, Electronic Arts, the Inter-American Development Bank, Deloitte, Bancolombia, Suramericana, Avianca, Ecopetrol, and Nomis Solutions.
