Expertise — Data & AI

Data Engineering & Artificial Intelligence Expertise

AI drives innovation, but data is its fuel. At Entité & Co, the XENA unit masters the entire value chain: from building robust data infrastructure (Data Engineering) to deploying custom predictive models (MLOps).

Talk about my Data projectSee the projects

End-to-end Data: Structure, Predict, Steer

A high-performing data ecosystem rests on three inseparable pillars:

Data Engineering (Structure)

Build solid foundations, from databases to Data Lakes, to guarantee the availability and security of information.

Data Science & AI (Predict)

Develop Machine Learning algorithms and leverage generative AI to automate and anticipate.

Data Analysis (Steer)

Turn raw data into visual, interactive dashboards for informed strategic decisions.

Areas of expertise

Three units, one value chain

From storage to decision: every building block is designed to fit with the others.

Data Engineering & Cloud Architecture

The technical foundation of your business. We design scalable architectures to collect, clean and store your large-scale data securely.

Data Architecture & Storage

Databases & Data Lakes
Design of relational (SQL) and non-relational (NoSQL) databases suited to your data flows.
ETL / ELT Pipelines
Automated flows to extract, transform and load data (Data Integration).

Cloud & Industrialisation (MLOps)

Continuous Deployment (CI/CD)
Automated releases to guarantee the reliability of applications and AI models.
Scalable Infrastructure
Containerisation (Docker, Kubernetes) and cloud resource management (Infrastructure as Code).

Data Science & AI Development

Advanced algorithmic solutions to solve complex business problems, optimise your processes and create new growth drivers.

Artificial & Generative Intelligence

Generative AI (LLM & RAG)
Integration of foundation models with your private data for innovative, secure solutions.
Natural Language Processing (NLP)
Sentiment analysis, semantic classification and knowledge extraction.

Machine Learning & Predictive Analytics

Predictive Models
Behaviour forecasting, scoring (e.g. churn prediction) and customer segmentation.
Evaluation & Optimisation
Model comparison and hyperparameter tuning to maximise performance and energy efficiency.

Data Analysis & Governance

Make your data speak, in full compliance. We turn your figures into visual strategic assets while keeping them secure.

Business Intelligence & Dataviz

Interactive Dashboards
Real-time steering interfaces built with Power BI and Streamlit.
Exploratory Analysis
Identifying hidden trends and extracting actionable insights for governance.

Data Governance & Security

Data Management
A data lifecycle (traceability, archiving) compliant with regulations (GDPR).
Quality & Audit
Continuous monitoring to ensure the data used is relevant and clean.

Projects & Use Cases

Projects delivered end to end, from the data pipeline to the model in production.
