My story

I'm a results-driven Amazon account manager and creative ads designer with a track record across e-commerce operations, wholesale sourcing, multi-account management and performance marketing.

I optimize Amazon stores end-to-end — from high-converting listing creation and inventory strategy to supplier vetting and brand compliance — and bring that same systems thinking into GoHighLevel: building funnels, pipelines, voice AI agents and chatbots that keep leads moving without a human touching every step.

On the creative side, I design lead-generation ads, manage social channels, and edit video and graphics for clients across HVAC, home services and local business verticals — including paid social campaigns for Regas Media's HVAC clients, Meta ads and short-form video for UK businesses with Ignite Agency, and Yelp profile and Yelp Ads management for North City Roofing.
