What I'm looking for

I’m looking to own paid media end-to-end, run rigorous testing with accurate tracking, and help scale revenue by improving CTR, CPC, CPA, and ROAS across Meta, Google, and TikTok.

I’m a Digital Marketing Specialist with 2+ years of experience managing paid media campaigns across Meta, Google, TikTok, and LinkedIn. I’ve owned full-funnel strategies (awareness → consideration → conversion) with an emphasis on testing, audience segmentation, and performance analysis—using results like 3.2M+ impressions, 500K+ reach, and estimated CTR between 1.8%–3.2%.

I focus on measurable growth: I’ve reduced cost per lead to $1.80 CPA, driven $96K+ in tracked revenue, and improved ROAS to ~2.7x through budget reallocation and creative testing. I also build reliable tracking infrastructure (GTM, Meta Pixel, Google Ads) for conversion-based optimization, and automate lead flows with ManyChat to improve response time and lead qualification.
