my most challenging project was when i worked on an ai-based natural language processing system to detect fraud in financial transactions. it required my team to build a hefty infrastructure to monitor large volumes of text data, along with a custom machine learning solution to accurately detect fraud patterns. additionally, since the system was deployed in a live production environment, we faced tight deadlines and had to be extra vigilant to ensure the reliability and performance of our system.
