Data Scientist with a Ph.D. in Experimental Nuclear Physics, seeking to leverage demonstrated expertise in building machine learning models, developing APIs, and creating data visualizations. Utilized LangChain and the Hugging Face platforms to develop chatbots and fine-tune Large Language Models. Architect efficient infrastructure on cloud platforms like AWS and GCP to deliver cost-effective data solutions. Dedicated on employing advanced analytical methods to derive valuable insights that drive data-informed decisions.

API Infrastructure Development: led the development of a robust API infrastructure, integrating Google Cloud Platform (GCP) services, SQL, and AWS Lambda. This integration enhanced the API's capabilities, improving efficiency and flexibility.

Real-time Data Mining: Developed tailored data solutions using automated web scraping pipelines, resulting in real-time data mining capabilities along with strong analytical and statistical skills contributed to a 60% increase in client satisfaction.

Data Visualization: Effectively communicated findings and solutions to clients through PowerBI and Google Data Studio analytics dashboards, resulting in a 70% increase in operational efficiency and cost savings.

Data Warehouse Integration: Led the integration of a data warehouse, optimizing data storage and retrieval using SQL. This initiative improved data retrieval rates by 40%, enabling faster and more informed decision-making.

Sentiment Analysis: Employed NLTK and Spacy-based Sentiment Analysis on customer reviews, resulting in a 25% increase in customer retention rates and a 30% boost in positive online reviews.

AI Chatbot Development: Leveraged fine-tuned GPT-3.5-turbo to create custom prompts for a database-driven chatbot, ensuring personalized and accurate responses from Google BigQuery.

Self-Projects:

In addition to my professional work, I undertook self-projects, including:

Document Question Answering Application: Developed an application on the ChainLit platform, enabling precise answer extraction from various document formats, enhancing user information retrieval.

Customized Chatbot: Created a customized chatbot using the Hugging Face API, optimizing interactions and facilitating dataset downloads. Users could train regression models with their datasets, selecting the best model based on performance metrics.

I hold a Ph.D. in Experimental Nuclear Physics from IUAC, Jawaharlal Nehru University, where I conducted in-depth research involving complex data analysis, time-stamped data handling, and calibration techniques. My work significantly reduced manual effort and increased operational efficiency.

Furthermore, I completed a Master's degree in Physics with a specialization in Quantum Field Theory from the Department of Physics and Astrophysics at Delhi University. This program deepened my understanding of theoretical physics and mathematical modeling.

I also earned a Bachelor's (Hons.) degree in Physics from Kirori Mal College, Delhi University, laying the foundation for my academic journey in the field of physics and scientific exploration. These educational experiences have equipped me with a strong background in physics, which I've leveraged in my data science and analytics career.
