Austria

Message

At Usenami, I built open-source signing infrastructure where exchange keys stay inside an AWS Nitro Enclave and each action is checked against policy. Real orders have been signed on Binance, OKX and Hyperliquid, and signed receipts let others verify both allowed and denied decisions.

I also built production infrastructure for paid AI-agent data access, including USDC payments and a partitioned market-data table. Before this, I spent over a decade in operations at one of Ukraine's largest retailers, becoming COO and Deputy CEO; I grew its online channel from under 3% to about a third of company revenue and built a third-party-seller marketplace.
