I am a hands-on Systems Architect and Technical Leader with a 15+ year foundation spanning enterprise virtualization & hypervisors (KVM, QEMU, VMware ESXi, OpenStack), bare-metal compute, distributed block storage (Ceph), and federal compliance (FedRAMP Moderate / DoD IL5), alongside over a decade mentoring and developing competitive robotic systems in real-time Python.

My defining strength is the ability to step into unfamiliar technologies, deconstruct them from first principles, and rapidly turn complex problems into reliable, working solutions—whether that means contributing upstream features to KubeVirt, defending a 6,000-node federal ATO under strict deadlines, or fabricating and programming an autonomous robot.

"Understand deeply from the ground up, approach platforms with rigorous testing and automation discipline, and turn unfamiliar complexity into clean, deterministic execution."

• Enterprise FedRAMP ATO Governance (Cisco Systems): Directed technical response defending HHS PMO FedRAMP Moderate Authorization to Operate across 6,000+ nodes during enterprise zero-day incidents (Log4j).
• Vulnerability Data Platform Architecture: Architected custom PostgreSQL, FastAPI, and Tableau data pipelines to automate compliance extraction across heterogeneous fleets, replacing manual audits.
• Enterprise Compute, Virtualization & Storage: Over 15 years administering bare-metal compute (Cisco UCS), hypervisors (KVM/Libvirt, VMware ESXi, OpenStack Nova), Ceph distributed block storage, and configuration management (Ansible, SaltStack, Puppet).
• QA Department Leadership & Systems Integration (StorageSoft / Phoenix Tech): Managed QA testing and technical support departments, designed heterogeneous multi-platform test labs, and acted as systems integration engineer ensuring interoperability with enterprise suites (Microsoft SMS, CA Unicenter).
• Foundational Systems Engineering: Rooted in airborne radar systems maintenance in the U.S. Air Force (AWACS), low-level disk diagnostic engineering, and mission-critical uptime.

A decade-long proof point of mastering unfamiliar domains across both physical hardware and real-time software:

• End-to-End System Design & Mechanism Automation: 10+ years mentoring and engineering in FIRST Robotics (Team 3160). Designing complete mechanical, pneumatic, and electrical subsystems, CAN bus architectures, sensor integration, and high-torque motor control loops.
• Production Python Software: Authored robot control architectures in Python (RobotPy, NumPy), implementing swerve drive kinematics, closed-loop PID control, state machines, and camera-based computer vision (AprilTag fiducials and machine learning object detection).
• Hardware-in-the-Loop (HIL) Subsystem Testing: Executed hardware-in-the-loop (HIL) testing on physical robot subsystems (actuators, motor controllers, and sensor arrays) to validate edge software behavior and control loops before full robot integration.
• Open-Source Modularity (FROGlib): Created and maintain an installable Python hardware abstraction library (pyproject.toml) that modularizes swerve kinematics, motor controller wrappers, and vision targeting across competition seasons.
• High-Pressure Tournament Diagnostics: Rapid, methodical root-cause debugging under tight tournament timeframes—isolating complex electrical noise, CAN bus faults, sensor drift, and code regressions in minutes.
