Charles Cezar

I’m a data-driven performance marketing manager with 10+ years of hands-on paid social experience, including personally investing over $200,000 USD of my own capital in Meta campaigns for my ventures. I focus on rigorous experimentation to continuously improve CPA and ROAS through disciplined testing of creative, audiences, and bidding.

I own full-funnel paid social programs (TOF/MOF/BOF) with deep direct-response and copywriting expertise, translating performance data into actionable creative direction, segmentation, and campaign structure. I’ve designed end-to-end funnels—including quiz funnels, VSLs, webinars, and email-marketing sequences—to move audiences from awareness through conversion.

Technology and AI are central to how I work: I build AI-assisted creative and market-intelligence tooling, generate and test image/video ad creative at scale, and integrate campaign data across systems via REST APIs. I’m also a Camunda 8 Certified Professional Developer, applying workflow automation and AI agent orchestration principles to marketing operations.

Beyond marketing execution, I co-founded a consultancy combining performance marketing, AI-driven software development, and process automation—training 20,000+ students across Brazilian and Spanish-speaking Latin American markets. Earlier, as a Federal External Control Auditor at the Brazilian Federal Court of Accounts (TCU), I built strong quantitative rigor and budget accountability through data-driven risk analysis and compliance reviews.
