VISION

• Craigslist meets eBay• Designed to make it easy for people to find others for

specific jobs, or alternatively, for people to get work• Buyers can list products/services they need• Sellers compete by offering lower prices or better services• Buyer is given a list of offers and can choose• Example: Bob needs someone to paint his house, and won’t pay more

than $50• Steve will paint it for $40• Mark will do the same job for $30• Roger will both paint the house and reshingle the roof for $100

• Filter listings by location/distance• Automatic filtering of illegal entries based on key words• Rating of buyers and sellers (to ensure workers get paid

and buyers get what they pay for)

SOFTWARE ARCHITECTURE

Apache

MySQL

PHP

HTML

• Components• Web server / PHP (web

page itself)• Database

• Account management

• Listing interaction• Content filtering• Sample Content,

Categories, etc.• Location based filtering• Ads

CHALLENGES AND RISKS

• Infrastructure • Front end needs to sync up with the back end• If they’re at different degrees of completion, you don’t know

whether your code is working or not.

• Interdependence between modules• Possible to create mock-up webpages, but the user:

• can’t test the webpage until the database is ready, and • can’t test the database until there is content to put in it

• Legal concerns • unwanted “services”• minimum wage exploitation
