The Brief

What you'll do, and what you'll demonstrate.

Build a compositional image-filter pipeline using higher-order functions plus 6 sample filters, with measured per-megapixel runtime.

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

Apply function composition as a real architectural pattern
Build a domain abstraction (Filter) that composes cleanly
Reason about per-pixel runtime cost of pure-function filters
Document an architecture so adding new behavior is cheap

Canonical roles

Frontend Engineer
Every button a user clicks, every loading state they wait through, every form that almost-but-not-quite works, all of it passed through a frontend engineer's editor. This is the discipline that decides how software feels. The role lives at a peculiar intersection of design empathy, performance budgets, and accessibility standards, which is why students who like both visual craft and systems thinking often find a home here. You'd grow into it by building real things in React or Next.js, reading other people's code, and developing taste for what feels right. Tools like GitHub Copilot accelerate the typing; the judgement about when to refactor and when to ship is still yours. Strong frontend engineers care that a screen reader can navigate their work.
