Available to hire
Hi, I’m Sri Maddinapudi, a data scientist with over 10 years of IT experience across data analytics, machine learning, and data visualization. I enjoy turning complex data problems into practical, scalable solutions that stakeholders can use to make informed decisions. I have strong expertise in Python, R, SQL, Azure ML, and BI tools, and I thrive in collaborative, Agile environments.
I’ve led end-to-end ML pipelines, automated data workflows, and built user-friendly interfaces (Streamlit, PyQt5) to enable analysts and business users. I’m always keen to learn and apply the latest techniques to improve outcomes in government, healthcare, and enterprise settings.
