Ai Agent & Quant Systems Engineer | Open Source: Alpha Airlock, Crucible, Signal Pulse
AI agent and quantitative systems builder with hands-on experience in Python, backend/API
development, crypto derivatives risk operations, workflow automation, and productionoriented internal tooling.
I build risk-aware AI agent infrastructure, structured research workflows, and automation
systems that emphasize reliability, auditability, deterministic evaluation, and operational
decision support.
Recently built and open-sourced Crucible, an agentic quantitative research workflow system
for strategy exploration, risk-aware evaluation, walk-forward validation, and structured
research automation.
Also built SignalPulse / Stage0, an API-first runtime authorization and guardrail layer for AI
agents and tool-calling systems. It evaluates intended actions before execution and returns
structured ALLOW / DENY / DEFER decisions.
My background combines derivatives / CFD trading risk operations, market monitoring,
exposure analysis, incident investigation, Python automation, and system-level workflow
design.
