$15-25 USD / hour

Needs to hire 5 Freelancers Add filters and sorts to a marketplace built on a react redux, node.js, lambda, dynamoDb, AWS stack. Our stack is purely functional, no use of object oriented programming. Sort & filter (by game & streamer name) for the marketplace - Sort by time left (least time left at top) - Sort by newest (most time left at top) - Sort by bounty amount (largest pledged amount at top, down to smallest) - Filter by game - Filter by streamer name Each marketplace listing has: - ID - Title (string, required) - Assignees (this can be 1 to 10 assignees, when filtering on assignee, we want all listings that contain the selected assignee in this object; assignees are picked from a finite set that contains millions of options; at least 1 is required) - Description (string, required) - Expiration date (this is what you'll use for "time left" and "newest") - Game (1, from finite set of ~20,000 options, required) Each marketplace listing has Pledges associated with it. The pledge object has: - pk - which is the marketplace listing ID - pledgeUserID - which is the user who made the pledge - amount - the amount that user pledged; bounty is the sum of all pledges made for one marketplace listing. If all goes well with this project, we'll keep giving you work with node, lambda, dynamoDb & AWS. Prior experience with optimization and performance would be ideal.

Hi there, I have read everything carefully & understood the scope of this project, as you have nicely explained whole functionality. However, it would be really good, if you can initiate the chat & talk before finalising the cost & timeline. I have also discussed with my technical team lead to make sure that there are no issues, so we are good to go & ready to start this project immediately. Please let me know how do you want to proceed, as I can also give you our team high level understanding paragraph to make sure that we are both on the same page in terms of requirements understanding. Just so you know I am flexible in prices, as quality & long-term relationship is more important. Look forward to hearing from you. Regards, YK LEADconcept
