I'm Dounia Toubal I turn raw, messy data into
systems that think, dashboards that decide, and APIs that deliver.
I'm a Data Analyst and Data Scientist with a Master's degree in Artificial Intelligence from USTHB, Algeria. My work sits at the intersection of data engineering, machine learning, and applied NLP.
I've built OCR systems that read Arabic and French documents, designed chatbot platforms powered by large language models, and automated BI pipelines that keep business decisions sharp and timely.
I care about delivering work that doesn't just look good in a notebook, but actually runs reliably in production. And when I'm not coding, I'm teaching — which sharpens my thinking as much as it helps others.
LLM integration, RAG pipelines, fine-tuning, and knowledge graphs for real-world applications.
End-to-end dashboards in Power BI & Tableau backed by solid ETL pipelines in Airflow.
Former Data Science instructor at GoMyCode, explaining complex things simply is a superpower.
A full-stack data toolkit ,from raw ingestion to production APIs to interactive dashboards.
Building real systems at the intersection of data, AI, and product.
Audited and rebuilt Power BI dashboards for a bank-partnered fintech platform. Built an Airflow ETL pipeline to automate data ingestion and ensure dashboards are always accurate and fresh.
Designed a chatbot builder platform API using FastAPI and Weaviate, enabling non-technical users to create LLM-powered conversational agents dynamically.
Built a multilingual OCR API (Arabic & French) to extract structured data from scanned official documents, with custom image preprocessing to maximize accuracy.
Delivered hands-on courses in SQL, Python, Machine Learning, and Deep Learning. Evaluated student projects and collaborated with the curriculum team to continuously sharpen course quality.
From data warehouses to regulatory AI — projects that go beyond the notebook.
An autonomous research pipeline powered by a LangGraph StateGraph with 5 specialist agents: Planner, Web Searcher, Synthesizer, Writer, and Grader orchestrated by a supervisor router. You type a question, it plans, searches the live web, extracts facts, writes a structured report, and self-reviews for quality. All under a minute.
Designed and implemented a production-grade data warehouse from scratch using the Medallion architecture. Built ETL pipelines, structured a clean star schema with fact and dimension tables, and exposed KPIs through BI-ready views.
Built an intelligent Q&A system for pharmaceutical regulatory compliance. Collected domain-specific datasets, constructed a knowledge graph of regulatory relationships, fine-tuned LLMs, and applied RAG techniques for precise information retrieval.
