I am a Chicago-based electrical and technology professional with more than 20 years in the electrical industry and extensive experience designing, building, and analyzing solutions for mission-critical Data Centers. My expertise spans electrical design, engineering, cost estimating, and project delivery, with a proven record of leading projects that improve efficiency, reliability, and sustainability. I bring deep field knowledge and genuine passion for this industry to every project, building robust, fast, and scalable systems that move the work forward.
Beyond delivering projects, I design and build new tools that solve problems this industry has long handled by hand, turning complex engineering workflows into software that is faster, more accurate, and repeatable. My work is grounded in engineering discipline, continuous learning and development, and sustainability, and I believe effective communication and clear, actionable feedback are essential to success. Every platform I build is secured to enterprise standards from day one, with two-factor authentication and role-based access control.
Live in Production
A full-stack, cloud-based platform I architected, built, and maintain end to end, powering estimating, change orders, timesheets, and progress tracking for mission-critical Data Center electrical construction. Secured with enterprise identity management, two-factor authentication, and role-based data access.
A modular suite of custom tools, including the Rapid Estimating Tool, spanning the full electrical project lifecycle: design, engineering, preconstruction, estimating, purchasing, labor, safety, training, and historical data, with third-party integrations connecting it all. Every module is built to fit the way a team actually works, like a custom-fit glove.
This tool automatically pulls and logs daily pricing for key materials like copper, aluminum, steel, and PVC. It provides a reliable historical data source for material costs and feeds the latest daily pricing directly into the Rapid Estimating Tool.
Simplifies the complex process of calculating electrical loads for mechanical equipment. Users enter equipment parameters, and the tool automatically calculates the results, including feeder sizing, circuit breaker selection, voltage drop, and ambient temperature adjustments.
This tool simplifies the process of calculating conduit and raceway fill. It accounts for different wire types and insulation ratings across all raceway types, and automates calculations based on the NEC and other relevant standards.
This comprehensive tool automates the process of sizing a generator and planning its fuel logistics. It calculates the optimal generator size based on current and future demand while also determining fuel tank size and refueling schedules.
New modules are always in development, bringing the same speed, accuracy, and security to every part of Data Center electrical work. Stay tuned for more announcements!
