Classify Retail Product Photos for an E-Commerce Marketplace
Overview
What this challenge is about.
Classify Retail Product Photos for an E-Commerce Marketplace. Beginner-friendly challenge in code. Writing production code that solves real engineering probl...
The Brief
What you'll do, and what you'll demonstrate.
Train an image classifier that beats the title-only baseline on top-3 category accuracy by at least 10 points.
This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Fine-tune a pretrained CNN on a small classification task
- Apply standard image augmentation for robustness
- Evaluate classification with top-1 and top-3 accuracy + confusion matrix
- Communicate results to a non-technical product audience

Careers
Career paths this challenge builds toward
Completing this challenge demonstrates skills that transfer directly to these roles:
Computer Vision Engineer
Fine-tuning a CNN classifier with proper splits and a non-technical writeup is the entry-level CV engineering task every product team assigns to a new hire.
This challenge sharpens
- image-classification
- transfer-learning
- model-evaluation
Machine Learning Engineer
Train/val/test discipline and clean evaluation are habits MLEs carry into every project; this challenge builds them on a small, tractable problem.
This challenge sharpens
- pytorch
- model-evaluation
- data-augmentation
AI Engineer
Translating model results into a memo a PM can act on is the AI-engineer skill that gets work shipped.
