At BJ’s Wholesale Club, I led and supported two technically demanding infrastructure improvement projects focused on rooftop mechanical systems. The first involved assisting in the assessment and replacement planning of aging rooftop HVAC units, where I evaluated structural load considerations, electrical integration requirements, and system efficiency improvements to ensure compliance with operational and safety standards. The second project centered on coordinating the installation process, including contractor communication, equipment staging logistics, and verification of proper mechanical and electrical connections. These projects strengthened my experience in real-world engineering problem solving, cross-disciplinary coordination, and executing upgrades within an active commercial facility while minimizing operational disruption.
