Global Growth Marketing Lead

About

After years leading growth and analytics across apps and agencies, I’ve learned that the fastest path to business impact is clear instrumentation → trustworthy KPIs → disciplined experimentation → simple, self-serve stories that leaders can act on today. At MOAIS and earlier at PIXO and Growth Rocket Apps, I built the building blocks for that system and used cohort/funnel analysis and A/B testing to steer onboarding, channels, and product bets. The result: 3× MAU, 10× app growth, a +600% LTV increase (via a regression-based retention/LTV model), and agency-wide ops that cut average turnaround from 6 days to 3, enabling +40% client capacity. I’m now sharpening the BI/DS edge through UCLA Anderson’s MSBA—with a focus on causal testing, forecasting, and data storytelling that wins trust. What I do • BI Foundations: Event taxonomies, KPI design, governance, and self-serve analytics you can scale across teams. • Experimentation: A/B design/analysis, lift modeling, cohort & funnel diagnostics, promo/test readouts. • Decision Dashboards: Executive and team views that connect inputs → behaviors → outcomes (not just vanity metrics). • Growth Strategy: Channel mix, ASO, creative analytics, and budget allocation grounded in data Selected wins • MAU +300% by instrumenting events, defining north-star KPIs, and running a disciplined test backlog. • Retention 32% → 72% & LTV +600% using a linear-regression LTV/retention model to target promos and lifecycle. • 10× app growth (rankings, sales, App Store features) via content optimization + analytics. • Ops velocity: Cycle time 6 → 3 days; agency capacity +40%/quarter through workflow analytics and standards. • Revenue +750% across multi-client growth programs by hitting UA/CPA goals and scaling what worked.
