I'm a cybersecurity and B2B technical writer who helps companies turn complex technical topics into content their audience can understand and act on. I write about cybersecurity, AI, crypto, and B2B technology for companies that need accurate, well-researched content. I help security vendors, startups, research teams, and technology companies create content that educates buyers, supports marketing goals, and explains technical concepts without losing accuracy. I don't simply rewrite documentation or summarize vendor announcements. My approach starts with research.

My writing helps readers understand not only what something is, but why it matters, how it works, and what decisions should be made because of it. Selected topics I've written about include: • Vulnerability research and CVE analysis • Threat intelligence and adversary activity • Threat-Led Defense • Exposure management • AI security • Cloud security • Security operations • Crypto security and blockchain risks • Security tools and platforms What clients value most is my ability to bridge the gap between technical depth and business understanding. I can work from research papers, technical documentation, threat reports, product materials, or subject matter expert interviews and turn them into content that serves both technical and non-technical audiences. If you need technical content that is accurate, well-researched, and written for real-world readers, I'd be happy to discuss your project.
