I am an AI Growth Engineer and the sole marketing owner for multiple B2B SaaS products, reporting directly to the CEO. I own end-to-end growth including AI search visibility (Google AI Overviews, Perplexity, ChatGPT), SEO, content systems, paid acquisition, marketing automation, and website performance.I define growth strategy, execution priorities, and success metrics independently and am accountable for inbound leads, CAC, and pipeline contribution. There is no internal SEO, ads, or content team; I own strategy and execution end to end.My work focuses on building durable growth systems through AI-first SEO and AEO, technical optimization, scalable content operations, and automation using n8n.I work best in environments that value autonomy, speed, and measurable outcomes.
