What I'm looking for

I seek fully remote, location-flexible roles where I can apply commercial insight, research-driven growth, and autonomous execution to scale revenue and operations.

I am a commercially driven business professional with over 10 years' experience across sales, market research, business development, operations, and entrepreneurship. I have a proven track record of building and scaling businesses from a cold start, turning research and data into revenue-generating strategies, and operating autonomously across distributed teams.

I co-founded and scaled a nationally recognised real estate business, led market research and go-to-market strategy, managed operations and recruitment, and executed digital marketing to drive sales and growth. I excel in remote-first environments, asynchronous collaboration, CRM and performance tracking, and I'm seeking fully remote, location-flexible opportunities where analytical insight and execution excellence are valued.
