I’m an IT PMO Intern at Corsair, where I lead end-to-end project timelines and partner with C-Suite to drive operational readiness for high-impact rollouts. I also led an “LLM & RAG” initiative by guiding the PMO transition for an internal, secure enterprise document assistant.

In parallel, I build hands-on security capabilities through adversary emulation and detection work—simulating Living off the Land behavior and monitoring detections in OpenEDR to understand process-tree signals. I’ve also used Wireshark and network segmentation (OPNsense + VirtualBox) to model recon and lateral movement safely.

On the AI side, I architect multi-agent pipelines using serverless GPU compute (Modal) to generate MITRE-mapped synthetic Red Team command datasets. I ground LLM prompts with real MITRE definitions and use parsing/validation strategies (Regex, RAG injection, and error-handling) to keep dataset quality high for Blue Team training.
