Most AI projects don't fail because of bad code — they fail because nobody checked if the results can actually be trusted. I build and validate intelligent systems: agentic pipelines, LLM-powered workflows, and the evaluation frameworks that make them safe to act on. My work sits at the intersection most engineers avoid: where technical results meet real-world accountability. Recently, my focus has expanded into agentic AI engineering and AI security — designing multi-agent systems with built-in quality loops, hallucination detection, bias auditing, and compliance filters. I don't just build pipelines; I build pipelines that check themselves. I've worked across computer vision, NLP, OCR pipelines, and clinical/academic research — including cell classification, ASR data, and publication-ready statistical analysis. Where I add the most value: — You need an agentic system that produces outputs you can actually trust and act on — You have a model or dataset and need to know if it's reliable before it goes anywhere near a decision — You're writing a thesis, paper, or clinical report and need analysis that survives peer review — Your stakeholders need to understand what the AI actually found — and what it didn't — You need an honest assessment of where your AI system could fail, be gamed, or cause harm I'll tell you honestly if ML isn't the right solution for your problem. That's rarer than it sounds.

I build data pipelines and AI systems that actually work in production, not just in notebooks. Soon to join Airbus as a Data Scientist focusing on Generative AI and NLP, I combine industrial-scale problem-solving with advanced academic rigor. Backed by a Master's in Data Engineering & Analytics and 3 R&D contracts at IRIT (France's top CS lab), I bridge the gap between cutting-edge research (LLMs, Deep Learning, Predictive Modeling) and high-stakes, real-world delivery. What I do: → Web scraping at scale : multi-source, anti-bot, JS-heavy sites (Playwright, Scrapy, BeautifulSoup) → ETL / ELT pipelines : from raw data to clean, structured, ready-to-use datasets → LLM & RAG agents : LangChain, Mistral API, ChromaDB, Ollama → Predictive ML : classification, regression, anomaly detection (XGBoost, CatBoost, PyTorch) → Explainability (XAI) : SHAP, Grad-CAM, attention maps (I make models interpretable) I published a machine learning project on aerospace engine degradation (NASA Turbofan dataset) on Medium / Level Up Coding. My research work at IRIT covered NLP, computer vision, and ML interpretability across interdisciplinary teams. I deliver clean, documented, reproducible code. I communicate clearly and hit deadlines. Available for short missions (a few hours) and long-term collaborations. Let's talk.
