What I'm looking for

I’m applying financial-grade security-by-design to LLM applications and autonomous agents, building agentic AI systems that can handle real money and real risk.

At VELVET.CAPITAL, I owned core DeFi protocol work from architecture through four audited releases, securing $7M+ TVL across four EVM chains. I architected a tokenization mechanism that represents users’ proportional shares as tradeable index tokens.

I integrated more than 10 third-party DeFi protocols and built cross-chain bridging infrastructure with deBridge. I also led security ownership across nine audit cycles and built core-contract test suites with 90%+ coverage.

I’m now applying a security-by-design approach to LLM applications and autonomous agents, including RAG, fine-tuning, and multi-agent orchestration. Earlier at MSG SYSTEMS, I developed an open-source compliance strategy and built a prototype web application for automated license checks.
