5 Data Science Projects to Boost Your Resume


Data science is both an exciting and a super competitive field to break into. And working on interesting projects can help you stand out.

For every data science job listing, a large pool of candidates apply—typically several hundreds—hoping to get shortlisted for the next steps. Almost all of them have a similar skill set—proficiency with libraries, tools, and and programming languages. But projects differentiate strong candidates from the rest. So how do you become one of those candidates?

Well, you should work on projects that help you showcase both your understanding of the problem and proficiency over the end-to-end data science project life cycle. When you work on projects:

  • Use real-world datasets .
  • Demonstrate technical expertise from data collection and cleaning up to building dashboards and deploying the models as needed.

This is a list of find data science projects that help you go beyond the generic and make your resume better.

1. Customer Segmentation

Understanding the customer base is essential to run a successful business. The objective of customer segmentation is to identify groups or clusters—segments—among customers based on their purchasing behavior to create targeted marketing strategies. You can use the Online Retail dataset from the UCI Machine Learning Repository for this project.

Start with appropriate data cleaning steps: handle missing values and ensure data consistency. Perform exploratory data analysis (EDA) to understand the different features and their relevance. Create features to indicate total purchase amount, purchase frequency, and recency for Recency-Frequency-Monetary Value (RFM) analysis. Use clustering algorithms like K-Means to segment customers based on their RFM scores. 

In addition, profile each segment by analyzing key characteristics and try to suggest targeted marketing strategies for each customer segment. Here’s a step-by-step tutorial that walks you through customer segmentation—using RFM analysis and K-Means clustering—on the Online Retail Dataset: Customer Segmentation in Python: A Practical Approach.

2. Customer Churn Prediction

Customer churn prediction helps businesses analyze their drawbacks and make strategic decisions to retain customers and improve customer satisfaction. The goal of churn prediction (as you’ve already guessed) is to predict which customers are likely to cancel or stop using a service. The Telco Customer Churn dataset from Kaggle is a good dataset to use for the project.

As with any data science project, go through data cleaning and EDA steps. The dataset contains features on the services, customer account, and demographic info. Perform EDA to understand the data and get insights into customer churn patterns.

Build a machine model—use logistic regression, decision trees, and the like—to predict customer churn and evaluate the model. Identify the most important features influencing churn and visualize them using feature importance plots and suggest strategies to reduce churn.

3. Market Basket Analysis

Market basket analysis helps identify products that are frequently bought together to improve cross-selling strategies. You can use the Online Retail dataset from the UCI Machine Learning Repository for this project as well. Or you can find a similar dataset.

After preprocessing and exploring the dataset, implement association rule mining using the Apriori or FP-Growth algorithm to discover frequent itemsets and generate association rules.

Evaluate these rules and create visualizations like heatmaps and item frequency plots to understand relationships between items. You can then suggest product bundling and cross-selling strategies based on the results.

4. Movie Recommendation System

A movie recommendation system, if done right, can be a fun and interesting project to work on and add to your resume. In this project, you’ll build a model that recommends movies to users based on their preferences. I recommend using the MovieLens dataset from GroupLens to build a recommender system.

After cleaning, exploring, and preprocessing the dataset to make it suitable for downstream tasks, analyze it to understand user preferences and movie characteristics. Apply featuring engineering techniques as needed.

Build a recommender system based on collaborative filtering using k-Nearest Neighbors (k-NN)  or matrix factorization using SVD. Evaluate the recommendation system. Also try to build an interactive dashboard where users can input their preferences and receive movie recommendations. 

5. Sentiment Analysis of Customer Reviews

Sentiment analysis involves analyzing customer sentiment from product reviews to classify them as positive, negative, or neutral. For this project, you can work with the Amazon Fine Food Reviews dataset or the Women’s E-Commerce Clothing Reviews dataset from Kaggle or a similar dataset of your choice.

Begin with data preprocessing—including text cleaning—and EDA to understand the data and identify common themes and sentiment patterns in reviews. Convert text data into numerical representation using TF-IDF scores or word embeddings. Be sure not to skip feature engineering steps.

Use simple models like logistic regression or naive Bayes; you can also use BERT to predict the sentiment of review text. Analyze the results and report findings to improve customer experience and product quality based on sentiment analysis.

Wrapping Up

I hope you found a few ideas for your next data science project. When adding projects to your resume, be sure to highlight the key skills used as well as the importance and impact of your project.

In addition, showcase these projects on your GitHub profile or a personal project portfolio page and link to them in your resume. If you’re looking to break into data science, you may find 7 Steps to Landing Your First Data Science Job helpful.
