One canonical dictionary entry associated with Backend. Category associations do not create separate skill pages.
Overview
What Fastify refers to
Fastify is listed in ResumeITKeys as back-end technology or system design concept. Its exact scope can vary by organization and role, so read it alongside the employer’s stated responsibilities. The dictionary also maps Koa to this canonical entry.
A posting may mention Fastify in connection with service implementation, API behavior, integrations, or server-side operations. Check nearby verbs, deliverables, and ownership expectations; the term alone does not establish the expected depth or mean every employer requires it.

How to include Fastify in a resume
List it in Skills when it is relevant to the role and you can discuss your level accurately.
Show practical use in an experience or project entry: state the task, your contribution, and evidence.
Connect it to a specific project instead of repeating the keyword without context.
Describe proficiency plainly, such as coursework, a completed project, or professional use; do not imply a certification you have not earned.
Use the job posting's wording only where it accurately describes your experience. Avoid keyword stuffing.
