We are in search of a proven Discord Bot Development expert with superior experience in the Discord Javascript API (not in python) and solid understanding of backend development with PostgreSQL databases. The project entails building a complete Job Board system for Discord that supports the following features:

-- Setup of 2 separate channels (1 channel for job seekers to post their CVs and portfolios AND 1 channel for businesses to post their open jobs).
-- Adding custom searching and filtering features to assist job seekers and businesses with quickly finding talent and jobs.
-- Backed by a centralized PostgreSQL database, the two channels are both available freely to all community members.
-- Ability to add "payment options" for enhanced or premium listings on both channels. The payment options will be integrated with Stripe and tied to a user's Discord account.
-- Summary and Detailed views for easy but comprehensive searches.
-- Support for the creation of custom categories in order to facilitate the classification of job listings as well as a large variety of specialties for job seekers.

All in all, this project will require an individual who can basically run with ideas and will be capable of helping to design a visual experience that is comprehensive and very user friendly overall. Payment system experience is a must, and you should be extremely well versed in properly using GitHub and Slack. (For github we demand frequent and small commits that make management of a project much easier overall).

You should be a seasoned expert with respect to the overall Discord experience and will to push the boundaries to make a defining Bot application that is comprehensive. We also will need the associated backend management pages and have an overall vision that is very similar to MEE6 in terms of how the bot and it's backend and Server integration will work.

The bot will be commercially available for free for the initial release, but again will have paid features at the community level which can also be turned on/off. The ability to configure and customize across industries is a must, however, this first release for our community will be focused on the Internet/Web Design, Development and Creative Industry. (Something that all Upwork Freelancers should know well).

Thank you and Happy Bidding...

AutoPartHub is an online marketplace that helps people buy and sell car parts easily in the United States. Sellers can quickly list their car parts by entering their car's Vehicle Identification Number (VIN) or the make and year of the car. The system will then create a list of parts with pictures, prices, and tips for taking good photos. Our goal is to make it simple for sellers to list parts and for buyers to find what they need.

### Key Features

1. **VIN-Based Listing**: Sellers enter the VIN of their car, and the system automatically shows all the car parts with pictures, part numbers and descriptions.
2. **Automatic Pricing Suggestions**: The platform suggests prices for parts based on current market trends.
3. **SEO Optimization**: Our site is designed to rank high on search engines, making it easy for buyers to find parts.
4. **User-Friendly Interface**: The website is easy to use for both sellers and buyers.
5. **Photo Instructions**: Step-by-step guides on how to take good photos of car parts.
6. **Secure Transactions**: Safe and secure payment options.
7. **Customer Support**: Help and support for any questions or issues.
8. Nested Parts Listing: Sellers can choose to list parts as whole units or break them down into smaller parts. For example, an engine can be sold as a whole or parted out. If the seller decides to part out the engine, they can still list the entire engine, but if any internal part is sold, the whole engine listing is removed.
9. Sets of Parts: Sellers can list sets of parts, such as engine injectors, as a complete set or individually. If one injector from a set of six is sold, the listing updates to a set of five.

### Target Audience

- **Individual Sellers**: Car owners who want to sell spare parts.
- **Auto Repair Shops**: Shops that need to sell extra parts.
- **Car Enthusiasts**: People looking for specific parts for their cars.

### Project Goals

- **Market Penetration**: Make AutoPartHub the main place to buy and sell car parts in the USA.
- **User Acquisition**: Attract and keep many sellers and buyers.
- **Revenue Generation**: Make money through fees, premium listings, and ads.

### Technologies Used

- **Frontend**: Next.js for the user interface.
- **Backend**: Django for managing data and server tasks.
- **Database**: PostgreSQL for storing data.

Skills: Website Design, SEO, Link Building, Django, Next.js
