Back to original languageAbout Haddad
Your data is fragmented, your pipelines are unstable, your data warehouse can no longer keep up with your business growth? I help you regain control.
For over 15 years, I have been assisting organizations in the Banking, Finance, Telecom, and Public Sectors in designing, building, and optimizing their data infrastructures. My approach combines an architect's vision with operational execution – I don't just draw diagrams, I deliver production-ready solutions.
What I bring concretely:
- Design & redesign of data warehouses (dimensional modeling, datamarts, repositories)
- Robust ETL/ELT pipelines (Talend, Informatica, DataStage, dbt, Airflow)
- Reverse engineering, performance audit & data flow migration
- Advanced PostgreSQL, Oracle expertise (optimization, modeling, extensions)
- On-premise Big Data platforms (Hortonworks/Cloudera, Hive, Spark)
Available for long-term consulting, auditing, or integration missions in France and remotely; also available for contract/fixed-price missions.
