It has Good initial functions as the original idea BUT LOTS OF Improvements are required. I could not find a roadmap so going to list them here.

I will revise my review if there are improvements in the near future
1.) Upwork Job posts have much more information to filter out. I don't know if the API or data feed you receive have that information or not but for Upwork job posts, you should have the following filters
- If the potential Client is Upwork Plus OR not (A big thing if someone wants to reach premium clients only)
- Client's hire rate Percentage.
- Client's total spend.
- Total spend/Number of freelancers he hired
- Proposals Count
- Number of "Interviewing"

2.) Skills and Expertise based searches (Include OR Exclude Both)

3.) I am seeing lots of "Only freelancers located in the U.S. may apply." job posts. (I am based in India)
I don't think we can exclude them from searches without losing all other US-based job posts.

btw, Upwork does not provide these job posts to me in the original search results.

I have a few more suggestions. Some of them are a little advanced but doable and game-changer. I am ok to talk if you want to discuss it.
