Work Experience
Data Scientist II
Sanofi
- Reduced root mean squared errors (RMSE) by 25% and manual modeling time by 16-fold by developing and deploying a scalable AutoML app in bioprocess manufacturing using Python and Streamlit—significantly lowering operational costs.
- Boosted product yield KPI by 15% and achieved scalability across 2 to 10,000-liter bioreactors by streamlining manufacturing with Scikit-learn-based cross-scale ML models—reducing scale-to-scale variability.
- Increased processing efficiency by 40% and enhanced data-driven decision-making by designing and developing data pipelines using Azure: Databricks, Data Lake Storage, and Data Factory; Python; and SQL to generate drug trial analytics.
Senior Data Scientist
LTIMindtree
- Reduced maintenance costs by 40% and improved the mean time between failures (MTBF) KPI by 20% by designing and deploying an ML-based predictive maintenance model that uses logistic regression to predict steam generator failures.
- Teamed with three members to devise a scalable real-time pump health monitoring solution to plan the pumps' preventive maintenance, leveraging R programming for remaining useful life (RUL) modeling and Power BI for visualization and dashboarding.
- Developed a data solution to automate the process of equipment name extraction from industrial CAD drawings, employing PyTorch, Python-Tesseract OCR, and CV2 packages, eliminating manual interventions.
- Managed a team of three graduate engineer trainees and helped set goals and objectives, providing feedback and support.
Experience
NASA Turbojet Engine Failure Prediction
https://github.com/Sha661nk/NASA-Jet-Engine-Failure-PredictionEnsuring optimal performance and avoiding unexpected failures are essential in critical applications like NASA Turbojets. This project utilizes historical engine data to develop a predictive model that can forecast potential failures, enabling timely maintenance and increasing operational reliability.
Document Query Bot
https://github.com/Sha661nk/DocQueryBotThis tool simplifies document review by enabling users to ask questions and receive direct responses based on the information within the PDFs. The application leverages retrieval-augmented generation and generative AI models to generate accurate responses using prior information stored in vector databases, ensuring precise, contextually relevant answers drawn from the uploaded documents.
KYC Automation System
https://github.com/Sha661nk/KYC-AutomationThis system allows users to submit their personal details, photographs, and Aadhaar card scans through a user-friendly web form. It uses facial recognition to match the user's photo with the Aadhaar card and employs Tesseract OCR to extract and validate information from the card against the Unique Identification Authority of India (UIDAI) database. The system ensures that customers are onboarded only after all data points are successfully verified, reducing manual intervention and improving accuracy and efficiency.
