Most developers think accessibility and performance are separate concerns. They're wrong.

Every millisecond your database query takes directly impacts the experience for users who rely on:

• Screen readers waiting for ARIA live region updates

• Keyboard navigation that depends on instant page transitions

• Switch access where delayed feedback breaks the entire interaction flow

I'm a Web Accessibility Coach specializing in PostgreSQL query optimization. I've spent years at the intersection of these two disciplines, and I built this course to share everything I know.

What you'll learn:

• Read and interpret EXPLAIN ANALYZE like a PostgreSQL internals expert

• Design indexes specifically for accessible UI patterns (ARIA content queries, keyboard pagination, dynamic form validation)

• Eliminate N+1 queries that accessible component trees amplify

• Set up production monitoring with a11y-specific performance budgets

Who this is for:

Mid-level web developers and DBAs building accessible web applications backed by PostgreSQL. You should already know basic SQL and have some exposure to accessibility concepts.
