Web Application & Accessibility
StudyCards.app
A free flashcard web app where learners build decks on any subject, study them in order, reversed or shuffled, and share them with a community. Accounts, private and public decks, favorites, ratings and view tracking, all running in the browser with nothing to install.
The brief
A flashcard app with real users and an existing database that had grown feature by feature. It needed to keep every account and deck intact while being made secure, accessible to keyboard and screen-reader users, and readable by search engines, with a reliable way to change the database schema on production without losing data.
What We Did
The approach
-
Built the full deck workflow: create and edit decks with validation and character limits, keep each deck private or public, and study in order, reversed or shuffled on any screen size.
-
Added community features: a searchable public deck library, favorites, ratings, and view counts so authors can see how often their decks are studied.
-
Hardened the application with CSRF tokens, a Content Security Policy, rate limiting on sign-in, sign-up and password resets, and a password policy that rejects commonly used passwords, plus emailed password resets.
-
Worked through accessibility across the site: labelled controls, a keyboard-operable navigation menu, real buttons for pagination, and study controls that work on mobile.
-
Introduced numbered database migrations and a script that moved existing production data into the new schema, so changes are tracked and applied safely.
-
Gave every page its own title, description and canonical URL, with structured data for public decks.
Outcome
The result
- Existing users and decks carried over into the rebuilt schema, and later schema changes are applied as tracked migrations instead of by hand.
- Accounts and forms are protected against cross-site request forgery, script injection and repeated sign-in attempts.
- Navigation, deck management and study mode can be operated by keyboard and screen-reader users.
