Overview
What this challenge is about.
Build a Visual Search Prototype for Sustainable Fashion. Expert-level challenge in code. Writing production code that solves real engineering problems, earn ...
The Brief
What you'll do, and what you'll demonstrate.
Prototype and justify a visual search system that lets shoppers find catalog items by uploading a photo rather than typing keywords.
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
- Extract image embeddings from a pre-trained convolutional neural network without fine-tuning
- Build and query an approximate nearest-neighbor index with FAISS for fast similarity search
- Evaluate retrieval quality rigorously using precision at k and recall at k
- Translate model performance metrics into a defensible estimate of business impact
- Package a machine learning prototype so another engineer can reproduce it on a laptop

Careers
Career paths this challenge builds toward
Completing this challenge demonstrates skills that transfer directly to these roles:
Computer Vision Engineer
This challenge mirrors the core work of a computer vision engineer: turning raw images into useful features and building retrieval systems that power real product discovery. You practice the exact pipeline of embedding extraction and similarity search used in industry visual search.

- computer-vision
- cnn
- embedding
Machine Learning Engineer
Prototyping a deep learning system end-to-end, evaluating it honestly, and justifying it to the business is the daily reality of an ML engineer. You leave with a portfolio piece that shows you can ship a working model and defend its value.
This challenge sharpens
- deep-learning
- faiss
- prototyping
Applied Research Engineer
Applied research roles reward engineers who can adapt pre-trained models to new domains and rigorously measure retrieval quality. This challenge builds that muscle by demanding clear metrics and reproducible experiments on a real fashion dataset.
