Hello. I have a custom built software that runs on ip rotation service company called "Proxy Rack"...however some of the request still gets block and i just need to make a few changes that are really simply for someone who knows C# programming. The software goes thought each link(3000+ links) and gets information such as price and stock. sometimes some of it gets blocked. If one link gets blocked, i want the software to request the same link again until it gets the information needed. More explanation will be given... This should be easy for someone who is good at c# programming

Hello, How are you today? I am confident I can make the minor changes to your data mining software. My understanding is that the software works fine, but you would like to make minor changes to what happens when a connection fails. Rather than simply failing, you would like to detect the bad connection, and rotate to a fresh working proxy and try and get the data again. A few questions if i may: 1) What is the deadline for completion? 2) How many times should the software retry a connection with different proxies? 3, 100, 1000, infinite? Choosing me as a developer is the right choice. I have a lot of experience with data mining websites and intimately understand the problems and solutions that can arise. Such as IP blocking, connection issues, javascript security, and rate throttling to name just a few. Most people on this website are part-time today and gone tomorrow. With myself you are not just paying for a project, you are making a business connection with a developer. A developer with over ten years of experience, that will still be programming ten years from now.

Hi, Your project sounds very interesting and I'd really love to work on it. I have over 15 years of experience as Physics and Math teacher, but I've also done a lot of both Excel and MS Word work (Macros, Templates, complex formulas), some web scraping using my software, desktop applications, web browser extensions, some Access and VBA work, etc. In my portfolio you can find some screenshots of application that I made for my school-related needs. I usually code my scraping software in C# and one of the main functionalities I implement is that the scrapper does not stop when it runs into a web page that it cannot open. In this case it will try to access the page in questions several times and if it does not succeed it will continue on to the next one. Of course it will make a new attempt at the "problematic" page once it is run again. Should you have any questions about me, my work or my experience, I'll be happy to answer. In the meantime, see my reviews and kindly consider my proposal. Kindest regards. Milan

Hello. I guess I have the qualification needed to solve this task. I have experience in C# and did some web scraping task with custom written C# app, so I should know what to do. Lets have a chat to understand each other better.

I have experience in scraping data from web from news articles and government sanction lists. That was a 10,000 rotation collection that included a job manager. It had retry functionality so that if one job failed, it re-tried a configurable amount of times, logged the error and moved on. A new re-try attempt would be done on the next rotation of that job. I have over 15 years experience in C#. This looks like a simple one to get me started in freelancer. I'm in your timezone as well for easy communication access. Thanks for you consideration!
