Data Analysis

Business dashboards, KPI analysis, and data-driven decision support

This section highlights my work in business intelligence, reporting, and analytical problem-solving using Power BI, Excel, SQL, and Python. The focus is on turning raw data into clear operational and financial insight.

Featured Dashboard

Retail Performance Dashboard

This project evaluates revenue, profitability, and customer behavior across categories and segments. The objective is to identify where growth is coming from, where margin pressure is building, and which areas deserve management attention.

Business Question

How are revenue, margins, and customer trends evolving across products, segments, and time?

Key Insights

Revenue growth was uneven across categories, with performance concentrated in a limited number of high-contributing areas.

Margin pressure can persist even when sales rise, so volume alone is not a sufficient indicator of business strength.

Customer and segment-level analysis helps distinguish broad-based growth from isolated performance pockets.

What I Focus On

Dashboard Development

Interactive reporting with decision-focused layouts, KPI cards, trend views, and clean visual hierarchy.

Business Metrics

Revenue, margin, growth, retention, customer behavior, and operational performance measurement.

Data Preparation

Cleaning, structuring, validating, and transforming data for reliable reporting and analysis.

Analytical Storytelling

Turning charts and model outputs into clear findings, implications, and action-oriented recommendations.

How I Work

1. Define the question

Start with the business decision the dashboard should support, not just the data available.

2. Prepare the data

Clean fields, standardize categories, validate measures, and create a structure that supports analysis.

3. Build the model

Create meaningful KPIs, comparisons, filters, and visual logic aligned with the business problem.

4. Deliver insight

Summarize what changed, why it matters, and what management or stakeholders should pay attention to next.

Data Work with Decision Value

My goal in analytics is not only to build visuals, but to structure information in a way that improves decision quality. Each project is designed to connect data, interpretation, and action.

Focus: dashboard design, KPI reporting, data preparation, and decision-oriented business analysis.
