Mustapha Ben Cherifa

Senior Product & Growth Analyst  ·  A/B Testing  ·  Retention  ·  Data Infrastructure

I help product and growth teams run better experiments, understand retention, and build the data infrastructure to do both reliably.

Four years in the most competitive analytics environments

I've spent my career in industries where data feedback loops are fast, the stakes are real, and teams that can't run and read experiments fall behind. First in mobile gaming at Voodoo and Popcore — where I owned analytics end-to-end for top-grossing titles — then at Rebuy, building the data infrastructure and A/B testing capabilities that power both product and CRM decisions.

I work best at the intersection of statistical rigor and business clarity. I build things that last — pipelines, frameworks, dashboards — and I do it with very little supervision required. My bosses tend to find that surprising.

From raw data to decisions that move the needle

⚗️
A/B Testing & Experimentation

Rigorous experiment design, statistical power analysis, and results interpretation. Including building the testing infrastructure for teams that don't yet have it.

📈
Retention & Behavioral Analysis

Cohort analysis, churn modeling, funnel optimization, and user journey mapping. Identifying exactly where and why users disengage — and what to do about it.

🏗️
Data Infrastructure & Pipelines

End-to-end pipeline design using dbt, Looker, and cloud data warehouses. Building reliable data foundations so teams can actually trust what they're looking at.

Tools and frameworks I've built

A/B Test Dashboard

If you don't test and control your data, you neither know whether your changes are effective, nor why. Worse — you might be actively hurting your own product.

A complete experimentation dashboard covering test setup, live monitoring, and results analysis. Built after watching product and CRM teams either avoid testing entirely or systematically misread their results. Based on real infrastructure built at Rebuy.

Channel LTV & Value Impact Model

Answers the question every growth and CRM team has asked: if I get X users into this channel, how much value does that generate over time? A transparent, flexible model for translating acquisition and engagement decisions into revenue projections — applicable to newsletters, CRM, push notifications, and in-app channels.

Let's talk about your data challenges

I'm available for B2B contracts and freelance projects — product analytics, experimentation infrastructure, retention analysis, or data pipeline work. I work autonomously and tend to deliver more than expected.
