100% work =100% payment 50%work=0% payment Don't bid if you don't agree. We have a huge database of 150 million songs, about 5million albums and artists. We also have a database of 250,000 radio stations. Currently a program has already been developed by previous developer to search which radio stations are active and to fetch metadata from these stations to indentify what song is being played on them. This program takes 10 secs for 40,000 radio stations. Your job is to read and understand the code already present and create a new program of fix the already present program to match and identify the metadata of radio stations with the database of 150million songs. Once the match is done you will be paid and then we can work on developing the api. The matching of the songs should be atleast 10,000 perfect matches per second.

Hello! Can do the software for you, no problem. But need to warn, to get this kind of processing speed you need a good hardware, a SSD storage and big memory, so the database can handle the searches from the software. It will be done in C++ with multithread, with all optimizations possible. If your hardware is the bottleneck on the system you need to pay, don't accept if you don't agree. I'm being honest and will do an honest work, and I'm sure you understand that the speed will depend on the hardware running it. Any doubts just chat, Thanks

I am very proficient in c and c++. I have 16 years c++ developing experience now, and have worked for more than 6 years. My work is online game developing, and mainly focus on server side, using c++ under linux environment. I used c++ to make many great projects, for example, I made the tools which can convert java files into c++ scripts, of course garbage collection included, this job is very similar to a compiler, and is very complex. I also made our own mobile game using c++, I can show you the demo of client, if you like. I am very proficient in java also. I have a very good review on Freelancer.com, I never miss a project once I accept the job, you can check my review. Trust me, please let expert help you.

My experience dealing with huge volume of data in an 24/7 environment and my knowledge in algorithm logic optimization make me confident that I can tackle this challenge. If I succeed reach the rate of 10.000 perfect matches per second of song already fetch from your data source with the existing algorithm.
