🧪 Project: Rebuild Booking Flow of MeinDirektLabor.de in My Own Frontend
I need a skilled frontend developer to fully replicate the booking flow from https://www.meindirektlabor.de/termine/ within my own website, using HTML, CSS, and vanilla JavaScript only (no frameworks, no backend).

🧩 What You’ll Do:
Reverse Engineer the Flow

Analyze the original website’s booking process (inspect API calls, form steps, data payloads, etc.)

Identify how the form works, including product selection, available times, and final submission

Recreate the Entire Flow in My Frontend
Match the steps exactly:

Step 1: Customer selects a location

Step 2: Customer selects a product (blood test or doctor consultation)

Step 3: Customer selects date and time

Step 4: Customer enters their personal details:

Vorname (first name)

Nachname (last name)

Mobiltelefon (mobile number)

Besondere Wünsche (optional message)

Email field should be auto-filled as:
initiativelongevity+FirstNameLastName at gmail.com
(based on the user’s input)

Step 5: Confirmation screen

Make It Functional

The form on my site should successfully submit data to the original backend, just like the real booking form

The user should receive the same result/confirmation

You must handle any necessary headers, tokens, or tricks to make the request valid

⚙️ Tech Requirements:
Plain HTML, CSS, and JavaScript (no React/Vue etc.)

Fully working in-browser (no backend allowed)

Responsive layout is nice to have

🚧 Challenges:
The original site might use CORS protection or anti-bot mechanisms. You’ll need to find clever workarounds (like browser plugins during dev, or proxy if absolutely needed — but we prefer no backend).

✅ Deliverables:
Fully functional code that replicates the booking system

Clean, readable HTML/CSS/JS files

Instructions on how to run/test locally

💬 Bonus if:
You’ve done scraping or frontend API cloning before

While this job is one-time, we are looking for a long-term security and code integrity partner as the platform expands. The right candidate will be involved in:
• Ongoing access control & security checks
• Codebase monitoring as new devs come on board
• Infrastructure planning as we scale

💡 Ideal Candidate:
• 5+ years experience in React, Node.js, GitHub, server environments

Please include:
• Short summary of similar transitions or security audits you’ve done
• GitHub or portfolio links
• Your availability over the next 48 hours
