I solve the engineering problems that show up on the balance sheet — leading teams to design architectures that scale under real traffic, and cutting what they cost to run by orders of magnitude.

Experience
- Lead a team of 5 engineers across the risk engine, simulation pipeline and cloud platform — owning architecture decisions, review and delivery.
- Built Chainrisk's Proof of Reserves over ~$1.5B in assets — attestations computed inside AWS Nitro Enclaves for hardware-isolated, verifiable execution, and proven with zero-knowledge circuits written in Circom.
- Extended the same proof system to real-world assets (RWA), bringing off-chain holdings under the same verifiable guarantees.
- Rebuilt the Monte Carlo risk engine in Rust with CUDA-accelerated kernels, replacing interpreted per-scenario execution with batched GPU compute: 60× lower cloud spend and 40× faster end-to-end runtime.
- Parallelised Solidity test-case execution across cores in Rust, taking Monte Carlo runs 16× faster by saturating available compute instead of running scenarios serially.
- Built AI agents that automate the risk-analysis workflow, turning a manual analyst process into a reproducible pipeline.
