Marketing leader at T&A Supply who built a four-agent competitive intelligence workflow for regional sales leaders.

United States

Message

At T&A Supply, I owned sales and marketing strategy, priorities, and budget while guiding a 20–30-person sales and marketing organization. I created brand positioning and sales materials, and directed website content, SEO, and email with agency partners.

I built a four-agent n8n competitive intelligence workflow with human review, delivering weekly market and competitor insights to regional sales leaders.

At Microsoft, I advised enterprise marketing and technical stakeholders on campaign workflows, automation, analytics, and customer journeys. My process redesign and measurement work contributed to 20% greater campaign execution efficiency and 15% higher conversion.

Across marketing operations roles, I developed lifecycle and demand-generation programs, CRM workflows, and sales enablement. At Salem Group, sales enablement was associated with approximately 50% more deals closed per sales call; my independent projects include marketing audit and research tools.
