Manager of Operations

I’m an Operations Manager with a track record of launching and scaling eight startup businesses across a wide range of industries — from franchise concepts and staffing agencies to logistics, property rentals, marketing firms, and even medical clinics specializing in plastic surgery and hair transplants.
My core strength is turning vision into structured, profitable operations. I’ve built businesses from the ground up, hitting aggressive sales goals, building high-performing marketing and ops teams, and scaling companies from single-site to multi-location success.
Whether it’s creating automation systems that boost lead conversion, setting up CRM workflows that nurture long-term clients, or building teams that move fast and deliver results — I know how to operationalize growth. I thrive in fast-moving environments and bring a blend of strategy and hands-on execution that gets businesses off the ground and into momentum.
If you’re looking for someone who knows how to take a startup from idea to impact — with a proven track record across multiple industries — I bring the experience, systems, and mindset to make it happen.More...
