About Me
Naresh Sampara, PhD
AI / Machine Learning Engineer & Data Scientist
Data Scientist with over 10 years' experience in Machine Learning, Data Science, Model Deployment, and AI Engineering. I have extensive experience applying Generative AI for data analysis, prompt engineering, report creation, document generation, chatbots, and building proofs of concept using large language models such as GPT-4, Llama, PandasAI, and Mistral.
I'm skilled in Tableau, SQL, and Python, with expertise building interactive dashboards and visualizations — including sunburst and network graphs — using Python Dash, Streamlit, and Plotly. I have designed, trained, and deployed deep learning (probabilistic, Bayesian) models for computer vision and NLP using TensorFlow Probability, and built end-to-end machine learning pipelines for custom models.
My recent work spans multi-agent RAG systems, document intelligence, LLM-driven classification, and cloud-native orchestration across banking, government, agriculture, telecoms, and public health — always with a focus on turning research-grade AI into reliable, production-ready systems.
