Karthik Reddy Mettu | Data Scientist

About Me

I'm a data scientist with a passion for turning complex data into clear, actionable stories. With experience spanning healthcare, education and finance, I use Python, SQL and visualization tools to uncover insights that drive strategic decision‑making. I thrive on building scalable pipelines, crafting interactive dashboards and mentoring teams in data storytelling.

Outside of work you'll often find me exploring new technologies, writing about analytics and participating in community events. I believe that effective communication is just as important as technical expertise, and I enjoy making data approachable for everyone.
