WORK HISTORY
Growth Analyst @Pflegia
Berlin, DE
Owned funnel analytics and experimentation for key growth journeys (registration → invites → acceptance → hires) using PostHog + GA4, translating insights into product changes and measurable KPI uplift. Led A/B tests end-to-end (hypothesis, instrumentation, QA, analysis, rollout) across key surfaces (homepage messaging, job card variants, lifecycle messaging), achieving an ~80% success rate and driving measurable growth improvements. Built and productionized the Smart Invite ML model, replacing rule-based matching; deployed a FastAPI service as a Docker image to ECR, connected via AWS Lambda (Function URL endpoint) with CloudWatch logging—improving invite acceptance (~56% relative) on sent invites. Owned the marketing measurement stack end-to-end: implemented and QA’d GTM + Segment event tracking, standardized UTMs / registerOrigin / registerMethod, and enabled reliable paid-channel attribution (Google Ads offline conversions + partner pixels) to support ROI-driven budget allocation and performance optimization.
