IZYU: Founder's Flagship Creator Platform Built and grown entirely from day one, I scaled IZYU from a basic product site into a global creator-marketing network spanning the US, EU, and SEA. I drove the 0-to-1 growth strategy, successfully onboarding over 4,000 creators through targeted paid ads and weekly email campaigns. Acting as the operational lead, I managed all UGC brand deals end-to-end—from initial client pitching and site development to creator vetting and final campaign delivery.

Singapore B2B F&B | Meta | Awareness Campaign The Objective The goal was to secure 1 million impressions over a 28-day period with a maximum budget allocation of SGD 2,500, requiring a highly efficient approach to ad distribution. Strategic Execution To maximize visibility without exhausting the budget, the campaign's core strategy relied on optimized audience targeting combined with strict frequency control. This ensured the budget was spent on reaching unique, relevant accounts rather than repeatedly serving ads to the same narrow audience, preventing ad fatigue and mitigating wasted spend. Key Outcomes The optimized campaign structure yielded a highly efficient $1.10 CPM, successfully delivering 1.09 million impressions. Ultimately, the strategic frequency capping allowed the campaign to surpass its primary reach goal using less than 50% of the total allocated budget.

Short-form UGC I scripted and produced in Indonesian for Kled AI to drive app awareness and installs. In the first 30 days, I grew two accounts from zero: 555K TikTok views and 1.2M Instagram views, 99% of which came from non-followers, so the reach came from the content, not an existing audience. I wrote every hook, set the pacing, and built each video around the install CTA. One reel hit 1.3M before Instagram restricted it. My focus was reach that converts to installs, not vanity metrics.
