Most brands with real traction have the same problem: acquisition is working but revenue isn't compounding. New buyers come in and don't come back. Funnels leak. Spend doesn't stack. I build the growth infrastructure that fixes that across acquisition, onboarding, retention, and the automation layer that connects them. In my most recent role as Head of Community and Growth at a live commerce marketplace, I ran the full growth stack simultaneously: Scaled daily GMV from under $10,000 to over $100,000 Took buyer retention from 25% to over 82% Managed $100,000+ per month in acquisition spend Built and led a 5-person team from scratch Recruited 100+ sellers to the platform Kept fraud and refund rates below 1% at scale That wasn't a lifecycle role. It was a full growth operator role paid acquisition, retention systems, community growth, product-adjacent work, and operations running in parallel inside a fast-moving platform. That breadth matters because revenue problems are rarely isolated. They're usually a sequence of small failures across acquisition, onboarding, engagement, and retention that compound silently. I find the sequence and fix it. What I do: Full-funnel growth strategy and execution across paid and organic channels. Lifecycle and retention systems Intercom. Customer io, AI-assisted sequencing. CRM infrastructure, lead scoring, and revenue-tied follow-up systems. Onboarding, activation, and re-engagement flows for ecommerce, marketplace, and SaaS. Paid acquisition oversight and agency/vendor management. Funnel audits, CRO, and A/B testing frameworks. AI workflow integration that connects strategy to execution without adding headcount. Analytics, attribution, and performance dashboards. How I work: I start with a diagnostic map the current funnel, find the highest-revenue leaks, prioritize the first fix that creates measurable impact. From there I build, document, and hand off systems your team can actually run. I work best with brands that have traction and need the operating layer between growth strategy and actual revenue. If you're still validating your product, I'm probably not the right fit yet. If the problem involves growth, retention, funnels, CRM, automation, or paid acquisition I can usually diagnose it in the first conversation and tell you exactly what I'd look at first.
