He designs and automates complex operational environments across Linux and Windows, with particular strength in clustering, load balancing, database administration, API integration, and production troubleshooting. Brad’s primary stack includes Python and Flask, and he has built automation for ServiceNow ticket resolution using statistical text analysis and NLP, including integrations with third-party systems and camera interfaces that lacked existing APIs. His experience spans engineering, reliability, systems administration, architecture, and consulting roles for organizations including Schwab through Mphasis, PayPal, GoDaddy, American Express, Verra Mobility, eBay, Cadence Design Systems, Wells Fargo, and Intel. He has managed or helped manage environments ranging from 60–100 servers to 20,000 Linux machines. Concrete accomplishments include upstream patches for autofs, cross-platform C ports, a Linux installer and Windows automation tools, Dockerized WebSphere and DB2 environments, high-availability designs using OpenBSD and Linux clustering technologies, and a negotiated approximately 90% annual reduction in Linux licensing costs. Brad is comfortable working autonomously, delivering on a weekly cadence, and participating in compliance-based code reviews. ## Services - Python \(Programming Language\) - Flask - Linux - Red Hat Linux -
