I'm a marketing manager and multi-channel marketer with 6+ years planning and executing campaigns that drive qualified leads, organic growth, and measurable results for US-based B2B, finance, and service brands. I'm comfortable setting strategy and doing the hands-on work across email, SEO, paid search, social, content, and landing pages, while owning day-to-day operations, project timelines, and performance reporting across multiple concurrent client engagements. I've grown a personal finance newsletter from zero to 40,000+ subscribers organically, with open rates nearly double the industry benchmark. My background spans regulated industries including healthcare and legal marketing, with a high bar for voice, tone, and accuracy. I use marketing automation (HubSpot) and AI workflows (Claude, ChatGPT, N8N, Make) to scale marketing systems and produce at the output of a small team. I'm Google-certified in project management, organized, analytical, and built for fast-paced, fully remote work.
