About Mounaim

AI Engineer graduated from École Polytechnique (State Engineer's degree in Data Science and AI) and holder of a Master 2 Data Science from Sorbonne, I have been designing and deploying generative AI solutions in production for 3 years, for a major group (Publicis), mid-sized companies, and start-ups.

Measurable results:

- Two B2B SaaS platforms delivered to production: IP AI assistant (patent drafting, prior art search) and educational platform with real-time voice tutor

- 90% accuracy on a multimodal advertising compliance tool developed for the Publicis group

- 50% reduction in manual work for tender analysis thanks to an advanced RAG system (HyDE, RAG Fusion, RAGAS)

- 70% reduction in manual data entry via an LLM pipeline for document processing for Swiss fiduciaries

Complete support, from design to deployment. I handle the entire chain: architecture, backend (FastAPI, PostgreSQL, Redis), LLM integration (OpenAI, Azure OpenAI, vLLM, open-source models), frontend (React, Next.js), and cloud deployment (Azure, AWS, Docker, Kubernetes). A single point of contact, from scoping to production.

Areas of intervention: business conversational assistants, RAG systems and autonomous agents (LangChain, LangGraph), document extraction and classification (OCR + LLM), real-time voice assistants, GDPR-compliant self-hosted solutions, MLOps and industrialization.

Accustomed to international environments (15 months in a distributed team with US clients, in English) as well as structured teams in large groups (Publicis Sapient, agile methodology). My approach prioritizes transparency: I validate the technical relevance of your needs before any commitment.

Experience

  • Mapbrain
    AI Engineer
    December 2025 - May 2026 (5 months)
    I designed and delivered 2 B2B SaaS platforms integrating production LLMs end-to-end, plus a part-time backend engagement on the MapBrain platform. I ensured the transition from AI prototypes (LLMs, autonomous agents) to production-ready applications.

    1 - SOTERIA — AI-Assisted Intellectual Property Platform (MapBrain - agency)
    A SaaS platform delivered as a white-label handover to an IP consulting firm. Features a conversational patent-drafting assistant (a guided 4-step chat generating an INPI/EPO draft), a multi-source prior-art search engine (USPTO / EPO / Google Patents), an INPI official-notification response generator, a GDPR-compliant self-hosted voice assistant, and a full multi-tenant back-office, enabling IP consultants to draft and manage portfolios faster.

    Tools: Python, FastAPI, OpenAI, vLLM, React 19, PostgreSQL, Stripe, MFA, Render

    2 - Copilot Comptable — Accounting Automation SaaS (MapBrain - agency)
    A document management SaaS for Swiss fiduciaries. A multimodal LLM pipeline extracts and classifies documents (invoices, statements, receipts), cutting manual data entry by 70%, while an email RAG lets accountants query client history in natural language, with Gmail/Outlook integration and Bexio / Crésus / WinBiz connectors aligned to Swiss tax formats, saving hours of manual bookkeeping per client.

    Tools: Python, FastAPI, OpenAI, LangChain, PostgreSQL, OCR (Tesseract), OAuth2, Docker, Render

    3 - MapBrain — AI Educational Platform (part-time backend) (Mapbrain - principal)
    An educational SaaS that transforms any document (PDF, YouTube video, audio, slides) into an interactive learning path: summaries, mindmaps, quizzes, flashcards, generated podcasts, and a real-time conversational voice tutor, letting learners absorb material in the format that suits them best. Deployed end-to-end on Azure.

    Tools: Python, Flask, FastAPI, LangChain, LangGraph, Azure OpenAI, AKS, Milvus, Redis, Socket.IO

  • ZAIVIO
    Generative AI Engineer
    October 2024 - September 2025 (11 months)
    Design of three generative AI solutions put into production for American clients, in a 100% English-speaking distributed team.

    Problem:US clients needed to move from idea to reliable AI product: monitor their online reputation, process complex medical documents, produce editorial content at scale, all without an internal AI team.

    Technical Solutions:

    Real-time e-reputation monitoring.Continuous multi-source collection (web, social media, forums), sentiment analysis by LLM, action recommendation engine, and automatic email reports. The client moves from impossible manual monitoring to actionable alerts.

    Medical AI Assistant. The challenge:long and technical clinical documents where an interpretation error is costly. Architecture combining autonomous agents and sourced RAG: each response is traceable to the exact passage in the original document, an essential condition for practitioners' trust. The tool concretely accelerates clinical decision-making.

    Automated editorial chain. End-to-end pipeline:detection of trending topics, generation of articles and visuals (DALL·E), scheduled publication on LinkedIn, X, and WordPress via their APIs. Zero human intervention between topic detection and going live.

    Three products, three productions, zero projects remained at the demo stage.

    Python, LangChain, OpenAI, autonomous agents, RAG, DALL·E, LinkedIn/X/WordPress APIs.

  • PUBLICIS Sapient Paris
    Data Science Consultant
    June 2024 - September 2024 (3 months)
    Paris, France

    Mission for Epsilon France for a project within the Publicis group.


    Design of a generative AI tool evaluating the ethical compliance of Publicis group advertisements within a team of +10 people, achieving 90% classification accuracy.

    Problem:Sales teams manually sifted through multi-page PDF tenders to extract response criteria. A slow, repetitive, and error-prone task, directly impacting the bid response rate.

    Technical Solution:RAG system developed with LangChain automatically extracting criteria from PDFs. Since the raw accuracy of a naive RAG was insufficient, I optimized it with advanced techniques: HyDE (generating hypotheses to improve vector search relevance) and RAG Fusion (merging multiple queries). Most importantly, I instrumented quality with RAGAS metrics (faithfulness, answer relevancy, context precision) and conducted systematic benchmarking (chunking strategies, top-k values, embedding models) to select the optimal configuration on real data. Because an AI system without quality measurement is not a production system. Result: 50% less manual work.

    Python, LangChain, OpenAI (GPT-4, GPT-4o), open-source LLMs, prompt engineering, Jira, Git.
