Need a Data & Generative AI expert for your complex projects?
As a former Senior Data Engineer, I now support companies on issues combining Big Data, generative AI, and intelligent automation.
With over 6 years of experience in designing data pipelines, optimizing Big Data processing, data quality, and industrializing large-scale solutions, I have worked in demanding technical environments using Python, SQL, Spark/PySpark, AWS, and Cloudera.
I notably participated in strategic projects at Cartes Bancaires, where I was the lead developer for decision support topics based on high business impact data analysis.
For nearly 2 years, I have also been working on generative AI and Machine Learning issues:
- AI Agents and intelligent automation
- Integration of LLMs in companies
- Predictive analysis and advanced data exploitation
- Industrial AI solutions connected to Big Data pipelines
My services include:
- Design and optimization of Big Data pipelines
- Development of generative AI solutions
- Industrialization of data and AI processing
- Automation and monitoring of processes
- Data governance, quality, and reliability
- Development of data-driven decision support solutions
I place a high value on clear communication, rigorous follow-up, and a results-oriented vision for every mission.
