Colin LEVERGER, Ph.D.
Ph.D. in AI/ML | AI Leader & Builder
AI leader and builder in cybersecurity: I own the AI roadmap and the technical strategy for LLMs at a bug bounty platform, and ship it, from the gateway underneath to agentic products in production.
Summary
Ph.D. in Time Series processing and Machine Learning (Orange Research & INRIA). Domain expertise spans LLM platforms and agentic systems, MLOps, predictive analytics, cloud platform design, and applied cybersecurity technology. Known for bridging research to operations with measurable outcomes, high-impact architecture, and pragmatic team leadership.
Career & Research Highlights
06/2026 - Now: AI Lead & Product Builder | YesWeHack
YesWeHack (bug bounty platform), Rennes - FRANCE
- Own the AI roadmap and the technical strategy for LLMs across the company's three AI priorities (triage, vulnerability management, AI pentest): from opportunity to proposal, specification and shipped feature, plus proposals of my own beyond the initial scope (AI pentest architecture, customer-side MCP access, AI governance). Defined the LLM operating model (gateway, mandatory tracing, guardrails, EU-only routing), now the path every AI feature goes through.
- Built and operate the internal LLM platform: LiteLLM gateway with SSO, budgets and multi-provider EU routing, Langfuse tracing, guardrails, production-readiness review.
- Shipped an agentic pre-triage assistant for vulnerability reports: pilot with triagers, evaluation gate and non-regression corpus, prompt lifecycle, production rollout.
- Architecture and product lead for an autonomous black-box pentest agent (engine teardown, V1 architecture, specifications).
- AI governance and security: CREST AI charter assessment, prompt-injection threat model, data residency and redaction.
