Experience

Data & AI Engineering Intern

Orange Senegal

01/2026 - Present

Designed and implemented a modern end-to-end Data Lakehouse architecture integrating storage, distributed querying, semantic transformation, and orchestration layers.
Built an open-source stack combining MinIO (immutable object storage), Trino (distributed query engine), dbt (semantic transformation), and Apache Airflow (workflow orchestration).
Introduced an agentic intelligence layer to move beyond static orchestration, enabling dynamic, adaptive, and resilient data pipeline management.
Led the development of a custom agentic orchestration framework that monitors pipeline health, detects anomalies, and autonomously adapts execution strategies to ensure reliability and performance.

AI Engineering Intern

Orange Senegal

07/2025 - 12/2025

Designed and implemented a RAG engine to enable augmented semantic search within the MAXIN mobile application.
Developed a document ingestion and indexing pipeline integrating storage, parsing, embedding, retrieval, and evaluation components.
Worked on optimizing retrieval accuracy, document chunking strategies, and evaluation metrics to improve answer relevance and reliability.

Data Engineering Intern

Orange Senegal

07/2024 - 11/2024

Designed and implemented a data lineage web application to manage and visualize database dependencies and metadata across the organization.
Modeled complex data relationships using a graph database architecture (Neo4j) to ensure data traceability and governance.
Developed backend logic and graph queries to track data flows, transformations, and interdependencies across systems.
Built an interactive web interface to enable visualization and exploration of data lineage paths.
