Experience

1. System Engineer

   Tata Consultancy Services

   Feb 2022 — Present

   Designed, built, and maintained scalable AI/ML workflows for training and deploying deep learning models. Designed a Natural Language to SQL query tool: Led the development of an application converts natural language input into SQL queries using OpenAI GPT-4 with Langchain, simplifying database querying for non-technical users. Developed an Agent in Langchain which will generate the questions and answers on Confluence pages of projects and provide it in CSV format to ingest it in Stack overflow to increase the Knowledgebase. Utilized Langgraph framework for RAG application: Implemented the Langgraph framework to develop a Retrieval Augmented Generation (RAG) application, improving data retrieval and automating content generation. Led POC projects, performed EDA and data preparation in Pandas, and presented actionable insights to clients.
