I build AI-powered marketing and sales enablement systems that actually ship. Not slide decks about AI strategy. Tools. My background is GTM and product marketing, with a specialty in complex B2B buying cycles. At McKesson (Fortune 10), I built enterprise buyer intelligence infrastructure used in company-wide sales training, including a 76-slide persona library and a full 5-stage buyer journey architecture covering a 7-to-13-month enterprise sales cycle. At Experts Exchange, a community of 5M+ IT and cybersecurity professionals, I built a newsletter from zero to 200K subscribers with a 60% open rate and $1.65M projected ARR. On the AI side, I build production systems, not prototypes. CRAM is a sales enablement and demand gen tool I built on Azure/OpenAI. CI Avenger is a multi-API competitive intelligence aggregator I built using the Claude API, Jina Reader, Firecrawl, and the X and Reddit APIs. My team used it weekly for conference and competitive prep. I also built a Deepgram voice-to-text research app for qualitative research processing. What I take on as a freelancer: - AI-powered sales and marketing workflows (pipeline research, competitive intel, buyer intelligence automation) - GTM strategy and messaging architecture for B2B SaaS and healthcare tech companies - Buyer persona and journey development for enterprise sales teams - Newsletter strategy and growth (audience monetization, deliverability, content systems) If you need someone who understands the GTM problem and can build the tool to solve it, that's the work I do.
