Shreyas Sachin Kulkarni

Shreyas Sachin Kulkarni I am an AI Systems Engineer and Data Scientist with an M.S. in Information Science from the University of Illinois Urbana-Champaign, where I graduated with a GPA of 3.93/4, and a bachelor’s degree in Computer Engineering with Honors in Data Science. My experience spans agentic AI, retrieval-augmented generation (RAG), machine learning, data engineering, and cloud-native systems. At Data Science Research Services, University of Illinois, I developed multi-agent RAG workflows using LangGraph and large language models, achieving 95% retrieval accuracy and improving Mean Reciprocal Rank by 50% through retrieval and chunking experiments. Previously, as an Associate Data Scientist at Apptware, I built GPT-4-powered applications, optimized real-time speech-to-text inference on AWS, developed deep learning solutions for medical imaging, engineered large-scale PySpark and SQL pipelines, and worked on real-time computer vision systems. My technical expertise includes Python, SQL, LangGraph, LangChain, PyTorch, TensorFlow, PySpark, FastAPI, Docker, Databricks, AWS, Azure, and Google Cloud. I am passionate about building reliable, scalable, and measurable AI systems that solve meaningful real-
