Most AI/ML projects work in notebooks — but fail in production. I build the ones that actually run. I’ve led production AI systems in real-world environments, including large-scale energy solutions for ENGIE Brasil. I design and deploy end-to-end AI systems that handle incomplete data, noisy signals, and real-world constraints. I’m a Data Scientist and AI Engineer with a Ph.D. in Cognitive Science and 12+ years of experience. On Upwork, I’ve delivered 25+ projects, $50K+ in earnings, and maintain a 100% job success score as a Top Rated Plus freelancer. My work goes beyond modeling — I build systems that integrate into real workflows. I’ve built: * LLM-based systems (RAG pipelines, AI assistants, internal copilots) * Automation agents and decision systems * Time series models for energy, anomaly detection, and predictive maintenance I work best with clients who want to build something real — not just experiments. If you already have data and a clear problem, I can help you turn it into a working system.
