NRAbout Nathan
With 8+ years of experience in AI products and professional services, I have a strong background in machine learning, software architecture & engineering, distributed systems, AI project and product management and economics.
I enjoy communicating strategically and synthetically with stakeholders, modeling complex business problems as optimization problems, and quantifying the success of the products we deploy. I have contributed to more than 15 AI projects for a dozen of large European, Asian and American companies, involving predictive maintenance, energy fraud detection, anti-churn, energy consumption forecasting, financial documents parsing or supply-chain resiliency. Some of these projects have generated significant return on investment, ranging from tens of thousands to hundreds of thousands of euros per year.
