Make the ad before you make the ad.

I turn a product link or rough idea into a sharp hook, timed script, visual beat sheet, on-screen copy, and structured, model-ready video prompts.

Proof of thinking, not inflated claims.

Every project below is clearly labeled self-initiated spec work for a fictional product. The point is to show structure, pacing, visual logic, and production judgment.

01 / SaaSSpec work

BriefLoop Meeting Assistant

A decision becomes a task, owner, and date—without a copy-paste chain. Built as a clean, 15-second product-demo rhythm.

04 / UGC VO Spec work

PlaySignal Parent Safety

A complete 30-second spoken UGC script for a fictional family-safety app. Self-initiated concept; no real product claims or results are implied.

“I used to hear the game from the next room and assume I knew what was going on.”

“But game chat is its own little world.”

“PlaySignal gives me a short alert when a conversation may need my attention.”

“Not a full replay. Not a reason to hover.”

“Just enough context to ask, ‘Hey, everything okay in there?’”

“Because the goal isn’t to watch every second. It’s to show up for the right one.”

How it works / 02

From rough brief to production-ready.

A compact workflow that separates product truth from creative invention and gives production a clear next move.

01 / FRAME

Find the real tension.

Audience, platform, approved claims, CTA, and the single behavior the ad should change.

02 / HOOK

Choose the entry point.

Multiple directions before polishing: problem-led, outcome-led, objection-led, or visual-first.

03 / TIME

Build every second.

Spoken copy, visual direction, on-screen text, pacing, and exact beat timing.

04 / HANDOFF

Make it usable.

Self-contained generation prompts, production notes, and a claim check for approved facts.

Services / 03

Small enough to start. Complete enough to ship.
