I am a passionate data analyst and a bit of a generalist, able to tackle cross-functional topics. I enjoy discovering what I do not know.

My work focuses on analysis: defining requirements, exploring data, building indicators, modeling, and decision-oriented reporting. Through my projects, I have strengthened my command of Python, SQL, and Power BI to deliver reliable, actionable analyses tailored to business context.

Implementation of DS-STAR

Agent framework for Data Science automation

PythonLLMMulti-Agent
Click for details ↻
Implementation of DS-STAR

Implementation of Google's research paper "DS-STAR: A State-of-the-Art Versatile Data Science Agent". This framework uses a multi-agent system powered by LLMs to analyze data, plan, write and execute code to answer user queries.

Key features:

  • Agentic Workflow: Pipeline of specialized agents (Analyzer, Planner, Coder, Verifier, Router, Debugger, Finalyzer).
  • Reproducibility: Complete saving of steps, prompts, code and results for auditability.
  • Interactive & Resumable: Ability to pause, resume and execute step by step.
  • Editing & Debugging: Allows manual code editing and includes an automatic debugging agent.

Implementation of ProFiT

Program search for algorithmic trading via LLM

PythonLLMEvolutionary Algorithms
Click for details ↻
Implementation of ProFiT

Reproduction of the ProFiT framework (Program Search for Financial Trading). It is an LLM-driven evolutionary search algorithm that autonomously discovers and improves algorithmic trading strategies.

Key features:

  • LLM-driven Evolution: Uses LLMs to act as "Analyst" and "Developer" to mutate strategies.
  • Replicable Algorithm: Strategies are represented as executable Python code.
  • Self-debugging: Includes a debugging loop where the LLM fixes syntax or execution errors.
  • Walk-Forward Validation: Implements cross-validation specific to time series.

Series-Search

Python API to search for TV series via their subtitles (Original/French)

PythonElasticsearchAPINLP
Click for details ↻
Series-Search

Development of a search engine that finds TV series from their subtitles. The project indexes 128 series and allows searches in original language (VO) and French version (VF).

Key features:

  • Advanced text search: BM25 subtitle indexing in a NoSQL database (Elasticsearch).
  • Data quality: Subtitle cleaning and preprocessing pipeline.
  • REST API: Interface to interact with the search engine.
  • Database: Indexing of 128 popular series.

RankFinder

Estimating ratings from customer comments via Deep Learning

PythonJupyter NotebookDeep LearningNLP
Click for details ↻
RankFinder

University project aimed at evaluating customer review polarity (Amazon, Spotify, etc.) to predict the associated rating. The objective is to help platforms better understand consumer feedback.

Key features:

  • Sentiment Analysis: Evaluation of the polarity of text comments.
  • Rating Prediction: Estimation of the score (rating) based on review text.
  • Machine Learning / Deep Learning: Use of learning models for natural language processing.
