Tobias Carvajal

I’m a Data Analyst with 3+ years of experience turning data into actionable insights across telecom, SaaS, and consulting. I’m driven by data-driven decision-making and measurable business impact—especially when it comes to improving customer journeys, conversion funnels, and retention.

In my current role as a Senior Data Analyst for e-commerce and public portals CRO, I analyze user behavior and funnel performance across app and web platforms. I’ve identified friction points to improve customer journey NPS by 3-5 points, and I lead end-to-end A/B testing from hypothesis generation through results analysis, improving key funnel conversion rates by ~8% to 12%.

I also use SQL to quantify user journey drop-offs and model revenue opportunities from proposed experiments, including identifying a ~$4M+ revenue opportunity by forecasting traffic and conversion uplifts. I partner closely with Product, UX/UI, and Research to translate quantitative and qualitative insights into testable hypotheses that drive business outcomes.

Previously, as a Business Intelligence Analyst at a regional SaaS organization, I automated reporting with Python and SQL—cutting reporting time by 70%—and built Power BI dashboards for product, sales, and operations. I also implemented an NPS comment machine learning classifier that contributed to a 10% improvement in user retention, and earlier I delivered KPI automation and stakeholder reporting as a BI Consultant in management consulting.
