What I actually do.

Full-funnel media buying on Facebook and Instagram, built around a testing structure that finds winning ads fast. Strategy, setup and daily optimization come from one person, the same one who engineers your creatives. No account manager relay, no handoffs.

Account structure · Testing roadmap · Test, kill, scale cycles · Clear weekly reporting

Performance Max and Shopping campaigns built for ecommerce, plus brand search that captures the demand your Meta ads create. One plan across both platforms, so your budget follows performance instead of sitting in silos.

Performance Max & Shopping setup · Feed optimization · Brand search protection · Cross-channel budget steering

The portfolio above is this service in action: statics engineered from buyer psychology, with hooks pulled from reviews and real customer language. Visuals are produced with an AI-first workflow, then finished with typography and layout craft in Figma. Start with a low-risk creative pack, no retainer needed.

Concept research · Hooks and angles · Figma typography & layout · Every format, ready to launch

AI UGC videos and AI animation ads, built for the feed. Scripts and hooks follow the same buyer psychology as my statics, and production is AI-first, so you get native-feeling video without shoots, actors or agency timelines.

Audit is in your inbox. Three things stood out: you only run bottom-funnel claims, every ad uses the same hook family, and your best seller has zero proof angles. Full teardown attached.

Okay, the teardown alone was worth it. Let's do the creative pack.

First six statics are in the shared folder: two hook families you never ran, plus one compliance-safe proof angle. Test plan is inside.

Week two update: the skeptic hook is your winner, clearly outperforming both control ads. I'm killing the two losers today and shifting their budget to the winner. Next batch iterates on that angle with fresh visuals. That's the rhythm from here: test, kill, scale, repeat.
