Back to original languageAbout Ismail
Do you need to structure, secure, or evolve your data pipelines?
With over 10 years of experience in data engineering, I support IT and business departments in designing, developing, optimizing, and architecting their data flows.
What I can do for you:
→ Design and develop your ETL pipelines (Ab Initio, Talend, Azure, SQL, Python)
→ Audit and optimize your existing processes (performance, quality, volume)
→ Implement data quality and governance frameworks
→ Lead your data teams (management, code review, best practices, Agile)
→ Support your data platform migrations (legacy to cloud, tool changes)
Why me?
I have delivered critical data projects at BNP Paribas (+120 jobs, ~10 GB/day), Savencia (Azure cloud migration), and Ubister (ERP connectors). I am not just a developer: I am a Tech Lead who knows how to communicate with the business, structure a team, and meet deadlines.
