About Ounnoughi

With several years of experience in data engineering and data flow automation, I implement efficient and high-performing solutions to optimize your data management processes. I primarily work on data pipelines, data integration systems, and custom applications to facilitate data exploitation.

My key skills:
Python: Development of tools for data processing and manipulation (pandas, NumPy, etc.)

Data Engineering: Design and management of robust data pipelines, data transformation, and large-scale database management.

Automation: Implementation of automated processes to improve the efficiency and reliability of data operations.

Knowledge Graphs: Creation and exploitation of knowledge graphs to structure and enrich data.

NLP (text processing): Development of solutions for analyzing and extracting data from textual content.

I have worked on various projects for companies such as TotalEnergies, EDF, Akkodis, and Groupama, where I developed tools and solutions based on data processing technologies and intelligent integration systems.

Currently, I am looking for short-term freelance assignments to continue diversifying my expertise and bring rapid added value to your projects. I can assist with specific needs, providing tailor-made solutions for your data management and exploitation.

Independent and pragmatic, I provide support on data, AI, or automation topics, with a client-oriented approach. I collaborate easily with teams to quickly bring value to concrete needs.

Available between 10 and 20 hours per week.
