1

Data Analysis

I explore and analyse datasets to find patterns and answer business questions. I'm comfortable working with real-world messy data — cleaning it, summarising it, and presenting findings in a clear way.
2

SQL & Database Querying

I write SQL queries to pull and analyse data from relational databases. I'm comfortable with JOINs, aggregations, subqueries, and working with multi-table datasets to answer specific questions.
3

Power BI Dashboards

I build interactive dashboards in Power BI to make data easier to understand. I use DAX for calculations and Power Query for data transformation — focused on making dashboards that are actually useful.
4

Python for Data Analysis

I use Python for data cleaning, analysis, and visualisation — mainly with Pandas, Matplotlib, and Seaborn. I've also worked with Scikit-learn for basic machine learning tasks as part of my coursework and personal projects.

Projects that showcase my expertise and creativity

View All

SUPPLY CHAIN & LOGISTICS (Data Economy Research Project)

This project was part of our Data Economy course—a collaborative research journey with a team of six. My focus explored how modern logistics comes alive through Operational Routing & Scheduling in Multi-Modal Systems, where data turns complexity into precision.

Advanced SQL Practice

A collection of SQL scripts I wrote while practising advanced querying techniques — including multi-table JOINs, subqueries, GROUP BY analysis, and data aggregation patterns.

Sales Performance Dashboard

Built a dynamic Excel dashboard to track 4 years of sales data — covering revenue trends, top products, and regional performance. Used Pivot Tables, charts, and formulas to make it fully interactive.

World Happiness Report Analysis

University homework project where I explored what factors most influence happiness scores across 156 countries. Covered correlation analysis, distribution checks, and basic predictive modelling.

Deutsche Bahn Delay Analysis

University group project analysing 1.9 million train records. I handled the statistical part — comparing delay patterns across train types using ANOVA and descriptive analysis.

Customer Churn Prediction

Built a machine learning project on 72,000+ ISP customer records to predict churn. Compared 6 classification models — Random Forest performed best at 93% accuracy. Done as a self-learning project on Kaggle.

Hello, I am

Ahmed

Introduction

I’m Tusar Ahmed — currently doing my Master’s in Management & Data Science at Leuphana University of Lüneburg, Germany.

I enjoy working with data. I’m comfortable using Python, SQL, Power BI, and Excel for analysis and visualisation — not at an expert level, but well enough to work through real problems and deliver something useful.

Before my Master’s, I worked in digital marketing for a few years, which helped me understand how data connects to business decisions. I’m currently looking for a Werkstudent or internship role in Data Analytics where I can keep learning while contributing to a team.

How I Approach a Data Project

Understand the Problem

01
I start by figuring out what question we're trying to answer. Then I look at the data — what's there, what's missing, what needs cleaning before any analysis can happen.
Understand the GoalExplore the DataCheck Data Quality

Clean & Analyse

02
I clean the data, handle missing values, and then use the right tools — SQL queries, Python scripts, or Excel formulas — to find patterns and answer the original question.
Data CleaningSQL / Python AnalysisStatistical Exploration

Present the Findings

03
I present results in a way that's easy to understand — a Power BI dashboard, an Excel report, or clear charts and summaries. The goal is always to make the insight useful, not just technically correct.
