1. Data Scientist

   Vitharka

   Jan 2025 — Present

   Designed and developed end-to-end machine learning pipelines for a retrieval-augmented chatbot by utilizing Python, FastAPI, and LangChain, and implemented initial experiments with scikit-learn and TensorFlow to test various model approaches for document ranking and information retrieval.• Contributed to the preprocessing and analysis of large-scale, multi-format datasets, employing pandas for data cleaning and transformation, SQL for structured data extraction, and using scikit-learn’s utilities for feature engineering and preparing high-quality model inputs.• Built, tested, and integrated REST APIs to deliver AI services, working closely with software engineers and product managers, and ensuring seamless deployment of ML models trained using scikit-learn and, for experimental tasks, TensorFlow and PyTorch.• Assisted in deploying AI-powered solutions—including scikit-learn and TensorFlow-based models—onto AWS EC2, actively monitoring model performance, troubleshooting real-time issues, and optimizing inference latency and resource utilization in the production cloud environment.• Continuously improved model performance by analyzing prediction outputs, gathering user feedback, and using scikit-learn’s evaluation tools to refine data preprocessing steps, thus increasing the accuracy and relevance of the chatbot’s responses.
