Data Analyst Specializing in EDA & ML-Driven Insights | SQL · Python · Power BI · KPI Tracking| Open to Data Analyst / Scientist Roles · West Bengal, India

Most data is just noise. I find the signal. Businesses collect mountains of data every day — but raw numbers don't make decisions. People do. My job is to bridge that gap. I'm a Data Analyst with hands-on experience in SQL, Python (Pandas), Power BI, and Excel. I specialize in exploratory data analysis and building machine learning models that don't just describe what happened — they help predict what's coming next. I've built end-to-end analytics projects tackling real business problems: from cleaning messy datasets and engineering features, to delivering dashboards that make insights impossible to ignore. What I actually do: — Turn chaotic, unstructured data into clean, analysis-ready datasets — Build dashboards and reports that give stakeholders clarity, fast — Apply ML techniques to surface patterns that gut instinct would miss. Statistical analysis and A/B testing support across product and ops teams — Cross-functional collaboration — I speak both data and business I thrive in environments where curiosity is valued, problems are complex, and the work actually matters. If you're hiring for a Data Analyst or Data Scientist role — or just want to talk data — I'd love to connect. 📩 Drop me a message. Let's see if there's a fit.
