I lead engineering, recruitment, security, and operations at GoQuant. I have evaluated thousands of candidates, run hiring bootcamps, and scaled the organization to 120 contributors at peak. GoTerminal is our institutional trading platform: multi-venue execution (CEX, DEX, OTC), market data, and risk, portfolio, operations, and settlement in production. 30+ integrations. Hybrid Rust, C++, Python, and web stack for low-latency execution and institutional workflow delivery. GoDark is a private, Solana-anchored execution network: fast, institutionally private trading without a trusted operator seeing every order. MPC-native matching, TEE-coordinated position and fill state, shielded custody with trading separated from settlement, compliance screening before privacy ingress, and operational controls (timelocks, monitoring, role separation) so no single key or operator can take down the system. • Lead engineering, recruitment, security, and operations across GoTerminal and GoDark • Evaluated thousands of engineers; ran hiring bootcamps; built and scaled the engineering organization • Managed up to 120 contributors at peak • GoTerminal: 30+ integrations; microsecond-sensitive paths with compliance and ops workflows • GoDark: private MPC CLOB, TEE coordination, Solana-anchored custody and settlement • Set standards for matching integrity, security posture, production operations, and incident response

Joined GoQuant as one of the first engineers and wrote the first lines of code for GoTrade, the high-frequency digital-asset execution platform that became the foundation for GoQuant's institutional stack. I owned infrastructure, deployment, and observability for low-latency trading from day one. Built the initial exchange connectivity layer, CI/CD and infrastructure-as-code for repeatable production deploys, and monitoring that tracked performance at microsecond granularity. Established latency benchmarking and regression practices with traders and quants, and translated desk requirements into buildable technical specs. Promoted to Head of Engineering within six months. • Early engineer on GoTrade; wrote initial codebase and production infrastructure for digital-asset execution • Architected low-latency trade execution infrastructure and the first exchange integration framework • Designed CI/CD pipelines for fast iteration without sacrificing production stability • Deployed observability and performance testing for sub-millisecond system metrics • Created infrastructure-as-code templates for consistent deployment and scale • Partnered with trading and quant teams on requirements, benchmarks, and delivery
