Experience

Data Scientist

LTIMindtree
Oct 2021 - Present · 4 years 9 months

• Independently and collaboratively designed and operationalized cloud-based machine learning pipelines on GCP, focusing on efficient storage solutions, Docker-based model training, and service endpoints for scalable inference.
• Significantly reduced inference latency and improved image similarity search accuracy for fraud prevention by engineering computer vision models using OpenCV, TensorFlow/Keras, and PyTorch, coupled with FAISS-based vector indexing.
• Enhanced text data analysis by developing and fine-tuning NLP models with BERT and Hugging Face Transformers for sentiment analysis, text classification, and keyword extraction, achieving high accuracy and performance.
• Developed a keyword extraction model for medical predictive analysis, enabling faster, more accurate diagnosis and treatment recommendations, and reducing manual annotation time by 80%.
• Collaborated with cross-functional teams to create a comprehensive testing suite for Ethical AI practices, focusing on the responsibility and sustainability of data solutions, including developing sustainability tests using the Cloud Monitoring API of GCP.
