I need a small, self-contained module that collects a user’s date of birth at sign-up and uses it to determine the correct access level for that account. The flow is straightforward: • Front-end: Prompt for date of birth, validate format in real time, and display any eligibility messages instantly. • Back-end: Store the date securely (hashed or encrypted at rest), tag the profile with the appropriate access tier, and expose a simple API call that lets other services check that tier without revealing the raw date. • Admin tools: Basic dashboard view so I can confirm the access level assignments during testing. Please keep the solution language-agnostic—I can plug JavaScript/React on the front and PHP, Node.js, or Python on the back depending on what you provide—but clean, well-documented code is essential. I’ll consider the job complete when I can: 1. Enter a birth date in a demo form, 2. See the user automatically assigned the correct tier in the database, and 3. Call the API endpoint to retrieve that tier without disclosing the original date. If you’ve implemented similar age- or DOB-based gating before, let me know; it will speed up review.
