I turn messy data into decisions people actually act on.

Hi, I'm Raj Kumar Sunar — a data analyst specialising in Python, SQL, and Power BI. I work across retail, finance, and tech to answer the question businesses keep avoiding: not "what happened?" but "what should we do next?"

My Philosophy

Analyst vs. Data Decorator 🎨

Early in my career, I thought visual complexity meant success. I focused on fancy slicers and complex charts. But in the vast field of data, stakeholders didn't need complexity. They needed answers.

The new roadmap: Target the Problem → Ask the Hard Questions → Synthesize pieces of information → Prescribe the Solution.

"Data is just the plural of datum unless you give it meaning. By applying rigorous analysis akin to the social sciences, I visualize solutions, not just numbers."

Test Project 113bca19

As part of my MSc Business degree, I conducted a strategic analysis of the competitive threats facing Tesla in the global EV market. Using Porter’s Five Forces framework, the project argued that although Tesla remained strong in technology and brand power, its market leadership was under growing pressure, particularly from EV-focused competitors such as BYD.
