Frontend Developer – Interactive Questionnaire (Immediate Start, UX + Visual Proposal Required) -- 2

Job ID: 40059267

Budget: €30 – €250 EUR

I have an already built HTML / JavaScript web application with finalized logic and user flow.
The application is fully functional and does not require redesign or logic changes.

I am looking for a developer to:

Deploy and integrate two versions of the same application:

A private full version (password-protected)

A public demo version (restricted functionality)

Ensure the demo version is derived from the full version (not rebuilt).

Implement PDF generation in the full version.

Implement email notification for form submissions in the demo version.

Add a provided logo to all pages and generated PDFs.

Apply small UI layout adjustments (positioning only, no style changes).

Perform light UX harmonization when integrating the app into an existing website (CTA consistency, spacing, fonts, colors).

The logic, structure, questions, and flow are already finalized and must remain unchanged.

Requirements

Strong experience with HTML, CSS, and vanilla JavaScript

Ability to work with existing code without refactoring

Careful attention to scope and instructions

Comfortable delivering within a short timeframe
