Custom E-commerce Website with AI Invoice Generator -- 2

I'm looking for a talented web developer to design a custom front-end and back-end website. The site will enable customers to select vehicle parts, and will fetch pricing data from another source via API. Ultimately, an AI system will generate a detailed invoice based on the collected data.

The project will involve the following steps:
1. Customer selection of the item: The customer will choose the brand, year and specific part.
2. Data fetching: The system will retrieve the original price from an external website.
3. Price calculation: The system will mark up the price with a pre-defined margin.
4. Invoice generation: A PDF invoice will be produced, showing itemized details.
5. Payment processing: The customer will complete their purchase through an integrated payment gateway.

Key features of the AI system will include:
- Calculating prices
- Generating PDF invoices
- Managing customer data

The website will be built using Custom HTML/CSS/JS, and the data source will primarily be API-based.

Ideal skills for this job include:
- Proficiency in Custom HTML/CSS/JS
- Experience with API integration or 1. Customer selects:
- Brand: Toyota
- Year: 2010
- Part: Brake Pads
2. The system fetches:
- Original price from RockAuto: $50
3. The system calculates:
- Price with margin: $50 × 1.5 = $75
4. The system generates:
- PDF invoice showing itemized details.
5. Customer completes:
- Payment via integrated gateway.
- Knowledge of AI implementation in web development
- E-commerce website development experience
- Payment gateway integration expertise

I look forward to your bids.
