I’m Rayen Ben Abdallah, an AI Engineer specializing in ML model development and agentic systems. I enjoy building end-to-end AI solutions—from training and evaluation to production deployment—using strong MLOps/LLMOps practices.
I’ve contributed to multi-agent platforms, built and deployed real-time vision services, and designed an AI monitoring platform for CO2 heat pumps with predictive analytics and explainable recommendations. I’m especially motivated by evaluating AI systems rigorously (including failure analysis) and turning insights into reliable, scalable products.

AI Monitoring Platform for CO2 Heat Pumps — FYP (AI/ML Engineer) at Tabreed (Remote, Canada)
February 1, 2026 - June 30, 2026Designed and developed a full-stack AI platform for real-time monitoring and predictive analytics of CO2 (R-744) heat pump fleets. Built and evaluated four ML models for COP prediction, leak detection, compressor-health forecasting, and energy-cost forecasting with strong predictive performance (e.g., COP R² = 0.97, MAPE = 3.3%). Integrated explainable AI (SHAP, Captum) and a hybrid RAG chatbot (ChromaDB + BM25 + Groq LLaMA-3.3-70B) with persistent memory for interpretable, live-data-grounded responses and automated prompt optimization. Deployed with JWT authentication, multilingual support (EN/FR/AR), Docker, and GitHub Actions CI/CD.
