What I'm looking for

I’m looking to lead performance marketing that combines technical tracking, automation, and experimentation to hit strict CPA/ROAS targets—while partnering with teams who value full-funnel measurement and ROI-driven reporting.

I’m a senior performance marketer with +5 years of experience building and optimizing high-budget ($100k+/mo) campaigns across global markets. I specialize in B2B SaaS, Healthcare, and E-commerce lead generation, with a strong focus on advanced lead nurturing automation and full-funnel tracking.

Across my roles, I’ve owned end-to-end paid media execution and technical measurement. I manage ad operations and experimentation across TikTok, Google, Meta, X, LinkedIn, Amazon, and Snapchat—pairing rigorous ROI-driven reporting with tight CPA/ROAS accountability.

My results speak for themselves: I reduced CPA by 40% while delivering a +3 ROI with a $1M annual performance budget, and I increased lead-to-appointment conversion rates by 25% through refined lead capture and remarketing funnels. I also built multi-market data pipelines, implemented server-side tracking to improve attribution accuracy, and automated reporting to save 10+ hours weekly.
