Frontend UI Cloning + Sandbox Flow Engineer (Training Environment)

⸻
Job Description
I’m looking for an experienced web developer to help me build a sandbox training environment that visually and behaviorally mirrors an existing consumer website without connecting to any real backend systems, payments, or credit checks.
This is for internal training only.
I already have:
• A working AI sales bot MVP
• Clear flow requirements
• Screens/pages identified
I need help specifically with frontend cloning + fake flow logic.
The sales bot mvp needs some cleaning up
⸻
Scope of Work
1. Frontend UI Cloning
• Clone the appearance (HTML/CSS/JS) of an existing website
• Multiple pages (product selection, cart, checkout, credit step, order confirmation)
• Visual accuracy matters (layout, buttons, text, spacing)
⚠️ This is UI-only — no real backend logic.
⸻
2. Sandbox Flow Logic (No Real APIs)
• Implement a training-safe flow:
• Select product
• Choose payment option
• Add to cart
• Checkout
• Credit step (fake)
• Order completed (fake)
• No real payments
• No real credit checks
• No external API calls
Behavior should feel real but be fully simulated.
⸻
3. Fake Credit / ID Logic
• Some payment options require:
• ID verification only
• ID + credit check
• Others require neither
This logic must be configurable (hardcoded config is fine for v1).
⸻
4. Frontend API Interception (Preferred, not required)
Bonus if you can:
• Intercept fetch / XHR calls from existing frontend JS
• Return mocked JSON responses so the UI behaves naturally
(This is preferred but not mandatory if you implement your own navigation logic.)
⸻
5. Clean, Safe Sandbox
• Clear “TRAINING MODE” banner
• No analytics
• No real endpoints
• Runs locally or via simple static hosting
⸻
Technical Preferences
You should be comfortable with:
• HTML / CSS / JavaScript
• DOM event handling
• Overriding fetch/XHR (mocking)
• Working with cloned/static sites (HTTrack-style)
• Debugging broken JS flows
• Optional: React knowledge (if needed)
⸻
What I Will Provide
• Exact website to mirror
• Page flow diagram
• MVP AI bot cleaned up
• Sandbox logic rules
• Feedback + quick decisions
⸻
Deliverables
• Working sandbox frontend
• Fake checkout + fake credit flow
• Clean file structure
• Short setup instructions
⸻
Timeline
• MVP version: 1–2 weeks
• Not rushed, but steady progress expected
⸻
Budget
• Fixed-price preferred
• Open to discussion based on experience
• This can turn into ongoing work if done well
⸻
