🚀 Principal Software Engineer | Technical Lead | 🤖 AI, ⚙️ Backend, ⛓️ Blockchain
Previously Amazon, SAP Business Intelligence, E*TRADE, and Consensys.
I have 18+ years in technical leadership and building software. I ship production systems, lead engineers, and work across the stack from enterprise BI to Ethereum protocols.
At Amazon I designed and shipped production systems for promotions and checkout at large scale — including the architecture for a distributed Promotion Service and a checkout migration in C/C++.
At Consensys I worked on blockchain protocol and developer tooling (Linnia / Stow: smart contracts, JS API, permissions, hackathon apps). Upstream work also landed in MetaMask (eth-sig-util) and MDN.
At SAP I worked on Business Intelligence / Crystal Reports and filed patents on reporting, statistical-language integration (R), mobile/QR-augmented reports, and document identification.
Earlier: senior software development at E*TRADE.
