Hello everyone 👋

I’m Cinta. I’m a Data Analyst with 3 years of experience working with SQL and Python.

I love analysing customer and business data to understand what’s really happening and turning those insights into actionable business decisions.

🔍 What I Do

🔸 Analyze structured business data to uncover profitability, pricing, customer, and operational insights
🔸 Write advanced SQL queries to aggregate, segment, and diagnose performance issues
🔸 Use Python (Pandas, NumPy) for data cleaning, transformation, and exploratory analysis
🔸 Build clear, decision-focused dashboards using PowerBI and Streamlit
🔸 Translate ambiguous stakeholder questions into measurable, data-backed recommendations.

🛠️ Skills & Tools

🔹 Programming & Databases : Python, SQL, PostgreSQL
🔹 Data Analysis & Visualization : Pandas, NumPy, Matplotlib, Seaborn, Plotly, PowerBI(PowerQuery,DAX), Streamlit
🔹 Workflow & Tools : Git, Jupyter Notebook, VS Code, PyCharm

📊 Projects

🔸 Retail Profitability & Pricing Analytics
🔸 Digital Wellbeing User Analysis EDA
🔸 Coffee Sales PowerBI Dashboard

⭐️ How I Work

I ask more whys than expected.
I like working backwards from business questions, breaking vague problems into clear metrics, and validating insights. I care more about clarity and impact than fancy models.
