Experience
Senior Data Scientist
PSA Singapore
Forecasted the vessel arrival for a longer time horizon using LSTM based on historic patterns, improving operational efficiency. Predicted the trajectory of the vessel using Attention based transformer, improving accuracy by 10%. Performed OCR on PDF data using Python, reducing manual hours. Analyzed container movements and used SQL and HiveQL.
Researcher (Data Scientist)
NEC Laboratories Singapore
Built LGBMRanker model to rank drivers based on risk profile. Performed clustering on driver profiles. Built Isolation forest anomaly detection and implemented custom metrics. Built a custom environment for traffic monitoring and pushed data via RabbitMQ. Built a Reinforcement learning model (DQN) for traffic light systems, improving traffic flow to ~14000 veh/hour. Filed a patent for Adaptive Traffic Control System.
