About Hamdi

Building AI models is useless if the input data is outdated or poorly structured. That's why I work at the intersection of Data Science and Data Engineering.

After 4 years in the corporate world designing, cleaning, and enhancing data flows, I now support companies as an independent consultant.

My goal is simple: transform your raw data into reliable business assets that your teams can directly use. My entrepreneurial spirit (I'm developing my own SaaS product on the side) drives me to deliver pragmatic code, focused on business logic and data quality.

I focus on the application architecture of your data, saving you from hiring two distinct profiles to code your pipelines and analyze your results.

My areas of expertise:
- Data Engineering (Software): Design of data pipelines (ETL/ELT), cleaning and processing of production data, database modeling (SQL/NoSQL).
- Data Science & Analytics: Exploratory analysis, development of predictive models, automation of reports and decision support.
- Product Culture: Translation of complex business needs into concrete technical solutions and complete autonomy on the code.

Why me?
- Dual Data Competence: A single point of contact to clean your data AND build your logical models.
- Autonomy & Pragmatism: Accustomed to developing products end-to-end, I know how to frame a technical need without requiring micro-management.
- Flexibility and Agility: Whether for a one-off project with a fixed scope (well-defined perimeter and deliverables) or for long-term support, I adapt to your constraints.
