What I'm looking for

I'm looking to build AI-powered marketing operations, content systems, and paid media programs that connect creative work, performance data, and business growth.

I've led paid media, content systems, and creative strategy for Mighty Dog Roofing, The Santos Law Offices, Michael Mendez, P.A., Galamedic, AMOLCA Editorial, and Pasteur Clinic. Across legal, healthcare, publishing, SaaS, and home services, I connect campaign performance, creative effectiveness, and lead quality.

At Mighty Dog Roofing, I managed more than $20,000 per month in advertising spend across Google Ads, Google Local Services Ads, Meta, Yelp, and Angi, while strengthening conversion tracking through GA4 and Google Tag Manager. At AMOLCA Editorial, I coordinated HubSpot rollout across five countries and grew the community by more than 10,000 followers overnight through a strategic page-consolidation initiative.

I combine AI-assisted workflows, process design, data analysis, and cross-functional collaboration to accelerate content production and improve operational efficiency.
