About Elias

I am a Senior Data Scientist and GenAI consultant helping companies and public institutions design, build, and deploy production-grade AI systems, with a strong focus on LLMs and agentic architectures.

I work end-to-end on Generative AI initiatives: from problem framing and use-case selection, to modeling, orchestration, evaluation, and production deployment.

My work typically involves:
- Designing and deploying LLM-based and agentic systems (RAG, tools, workflows, multi-agent setups)
- Building robust ML and GenAI pipelines with strong attention to reliability, monitoring, and governance
- Translating business and policy constraints into concrete, measurable AI solutions
- Supporting public-sector and regulated environments where rigor, explainability, and change management matter

I also advise leadership teams and train technical and non-technical stakeholders to ensure effective adoption of Generative AI at scale, beyond PoCs.

Available as a remote contractor. UK/EU time zones, short notice availability.

    RETAIL (LARGE RETAILERS)
    September 2024 - December 2025 (1 year and 3 months)
    Massy, France
    Second mission, directly under the supervision of the Director of Data Science:
    - Developed several PoCs, targeting production deployment after Executive and Director Committee validation
    - Worked in a 3-person squad (1 PM, 2 Data Scientists), with fast and efficient approach that fitted perfectly the needs to demonstrate our capabilities to create useful agents
    - Built SET 2.0, a PoC to automate the first-level analysis of retail opportunities for Carrefour (creation, extension, or acquisition of stores)
    - Used a multi-agent approach to evaluate key factors: competition, cannibalization risk, and topography
    - Used several technologies such as Agent Development Kit, Cloud Run, LangChain, geo-data calculus (for catchment areas and topography studies)…
    - Weekly meetings with each stakeholders to increase adoption and make sure to fit the business needs

    First mission, with the Pricing team:
    - Worked on the chaining algorithm of products to determine their optimal price
    - Conducting experiments, workshops and deployments to maintain and improve the current solution, while exploring new ones
    - Leading a GenAI experimentation with a Google Blackbelt to create a « Pricer » Gemini agent, then switching to a hybride architecture (classic ML algorithm + LLM for ambiguous cases)
    - GCP stack: Vertex AI (Datasets, AutoML…), Big Query (Data Form included), Composer

    - Relations Extraction with Few-Shot Learning Model, by exploring and optimizing state-of-art BERT vector combination techniques, reaching a minimum of 75% accuracy on complex real world data.

    - Making a NER Few-Shot model for a PoC, with deep debugging and analysis, reaching an overall ≈80% F1-score on OCRised production data (very noisy).
    - Deep Learning model in Java for Sentence Segmentation, to improve a custom rule-based NER solution.
    - Dataset Generation with auto-labelling using Generative AI (LLMs), to reduce the time-to-market by quickly fine tuning production models to customers-like documents
    - Designing and creating a whole pipeline about Active Data Generation (automating the Active Learning technique), to finetune a NER and a RE model automatically using a sequential augmentation technique with GenAI and a multi-agent approach until reaching threshold results
