About Nehdim

Data engineer with 5 years of experience, I assist companies in the design, implementation, and optimization of their data architectures.

With two specialized master's degrees, I have developed solid expertise in both technical and functional areas. I began my career as an IT consultant, where I worked for 2 years on various missions, allowing me to quickly adapt to different environments and business challenges.

I then spent 3 years at Dassault as a Tech Lead Data Manager, where I led high-value data projects. In this role, I managed teams, defined robust architectures, and contributed to the implementation of reliable, scalable, and performance-oriented data solutions.

Today, I work as a freelancer to help my clients:

Structure and leverage their data
Design performant data pipelines
Implement modern architectures (Data Lake, Data Warehouse, etc.)
Ensure data quality and governance

Rigorous, autonomous, and results-oriented, I quickly integrate into teams and bring a pragmatic vision to transform data into a strategic lever.
