My messaging strategies, marketing communication skills, and proposal-writing successes have generated more than $200 million in revenue and raised over $100 million in funding for publicly-held technology companies. I also provide expert technical editing for Fortune 1000 IT companies, legal editing for lawyers, and ghost-writing for executives to publish thought leadership articles in international media. I am an expert in crafting prompts for AI agents (ChatGPT/Claude) and refining and fact-checking AI output. I specialize in: - Marketing communications: articles for trade publications and national media; blogs and other web content for SEO; branding strategies, mission statements, and value propositions; case studies, white papers, sales presentations, and other collateral; proposals/RFP responses; market research and segment analysis. - Corporate communications: executive thought leadership pieces, press releases, and other earned media content; investor presentations, prospectuses, SEC documentation, and other IR content. - Technical, academic, and professional editing: IT product documentation and user guides; legal decisions and contracts; school/job applications, resumes/CVs, research papers, and thesis presentations.
