What I'm looking for

I'm seeking a Senior Director of Growth Marketing position at Outreach, where I can apply demand generation and account-based marketing to support measurable revenue growth through innovative marketing programs.

At Opterrix, I built CAC and LTV models to guide channel investment and budget decisions. I also ran email A/B tests that raised conversion from a 5–6% baseline to 15% with a targeted pilot-offer variant.

I built AEO into website content around ICP-specific questions and established a Reddit and Quora presence to improve LLM visibility. With AI-powered workflows, I grew the LinkedIn audience 200% year over year while scaling content output threefold on a two-person team.

Earlier, at John Clark Creative, I developed product marketing messaging and demo content for American Family Insurance stakeholders; that work evolved into the founding of Opterrix. At Weather Central, I managed a $250K trade show budget and introduced interactive demos that drove $5M in new pipeline and $2M+ ARR.
