At Fygg, a holistic oral care startup, I developed the brand's science-first voice from the ground up, translating clinically complex ingredients like nano-hydroxyapatite, L-arginine, and oral prebiotics into high-retention, education-first short-form content optimized for credibility and virality. Over six months, I established content standards that balanced factual precision with accessible language, ensuring the brand could hold its ground in a science-driven DTC market while remaining genuinely engaging to general audiences.

To accelerate creative production and optimize output quality, I independently designed a comprehensive prompt engineering strategy integrating Claude, ChatGPT, Perplexity, and Gemini. Using the RISEN method, I built modular, performance-tested prompts and applied an iterative RLHF-inspired feedback process to optimize language quality, narrative tone, visual sequencing, and retention-driving structure across models. This work gave me direct experience in building evaluation criteria, testing outputs against quality rubrics, and refining model behavior toward a defined creative standard.

My work supported Fygg’s creator-led community education strategy and helped seed its launch in a competitive, science-driven DTC market. Top-performing results:

• "If you're not brushing your teeth first thing in the morning" video: 4.1M views, drove a 15% lift in channel engagement

• Dentist reaction video: 1.1M views, established Fygg as a credible, expert-backed brand
