About Me

Rafał Paluszak

I transform raw data into competitive advantages. Building on 4 years of strategic experience at McKinsey & Company and a deep background in the banking sector, I design robust, scalable BI solutions that drive profitability and mitigate risk.

While my expertise is rooted in high-stakes financial environments, my analytical approach remains industry-agnostic. I apply a "So What" mindset to every dataset, ensuring that technology serves business strategy. I don't just build dashboards; I architect decision-support systems that are technically sound and strategically relevant.

Consultative Analytics Approach

I focus on the "Why" before the "How". This methodology ensures that every data point serves a clear business objective.

1. Strategic Discovery

Identifying core business questions and stakeholder pain points to ensure alignment with financial objectives.

2. Scalable Architecture

Designing robust data pipelines and Lakehouse structures using SQL, Python, and cloud infrastructure.

3. Actionable Insights

Translating complex models into intuitive visual stories. Prioritizing clarity and the "So What" factor.

4. Continuous Optimization

Refining models through an iterative feedback loop to adapt to shifting market and regulatory landscapes.
