About Yassir

👋 Hello, I amYassir Hanafi—2x Founder (BERBER House, +€800k Revenue / 18 months; BrodAI, SaaS SEO incubated at Station F)and a graduate ofCentraleSupĂ©lec**. This dual **tech + businessbackground gives me a ground-level perspective: I code your "Growth Engines", but more importantly, I know how they translate into profit.

Why I'm Different

- **"Founder First" Vision**: Every line of SQL, every A/B test has a clear P&L objective (CAC, LTV, margin).

- **Full-Stack Growth Engineer**: From BigQuery ETL to deployment, I cover the entire chain without depending on a dev team.

-Proven ROI**: +€800k in e-commerce sales, + **25% ROASthrough models that predict ROAS for each campaign (product category)

My Services

- Data Stack & Attribution

- BigQuery/Snowflake warehouse design, SQL + dbt pipelines, custom multi-touch model.

Dev & Infra

- Cloud & Data: Docker, BigQuery/Snowflake, dbt, Airflow

- Generative AI: OpenAI / Claude 3 integration, embeddings + vector store (PgVector, Pinecone) for semantic search and product recommendation.

Express Method
