We have a custom C# program that needs a few support items from an expert C# developer who knows SQL and API technologies well. The developers who built the application do not service and maintain the application, so I'm looking for an experienced and solid developer to handle an initial issue and potentially support it on an ongoing basis. Issue #1: We have data coming into our server via API that just stops unexpectedly. We presented the issue to our data vendor and they have verified via data logs that despite the stoppage, the data is still streaming. Our application does not handle the disconnection reason well, or reconnect if necessary, so we need this corrected. If this can be handled efficiently by a selected freelancer, we wish to have an ongoing relationship with you to maintain this program and potentially build additional enhancements. Prior to any work being done, we wish to select a freelancer with appropriate experience and then provide access to the code as well as discuss what changes will need to be made prior to doing any work.

Look, there can be various reason of the same. Until I will not dig into this it's really difficult to commit anything. I do not want to waste your time to be honest. If you can share the details or may if you can share the screen so that I can jump into it and check what is the issue, I can confirm you the rest. You will not lose a single penny until we are not 100% ready. I hope you can understand me and will ping me to discuss in details. Thanks

Ok, so from what I'm thinking, here are couple of possible solutions to the problem, since it seems like a common fix: 1. Introduce a fallback (there is none at the moment) 2. Introduce handshake - if that is suppose to be a mocked endpoint from which you're trying to stream data. 3. Enable timeout/thread based re-connection attempts with a threshold e.g. 3 attempts to reconnect & then it fails with error 4. Try-catch-finally block usage to log errors There are other things possible too, but have to discuss it in detail with you for better clarity. Drop me a message if this sounds interesting!

Hello, My name is Viktor. I'm developer (more than 10 years of experience in a field of web development, US and European companies) and owner of a small dev comapny in Krakow, Poland. We are developers and work with basically any type of coding, mostly focused on PHP/.NET and JS/HTML/CSS. But also have experience in doing Cordova, React Native and native Android and iOS apps. I can suggest you: team of developers so we will be able to replace/add developer in case of emergency. Hourly project with a $15/h, no pre-paid payments. We do as much work as you need and you pay only for work we do for you. If you want a fixed fee project, I can count a price for you. My role - quality control and communication. In our work, we use GIT to keep source codes and may set up a demo server for you so you can see changes we do ASAP and without deploying them to live site. Additionally, I'll send you reports once in a day or two showing hours spent and description of job that has been done. So, you can control your progress and budget easily. Before some new feature is done, we'll also send you possibly solutions (if we see more than one) with pros and cons and estimate. So you can choose best approach you need. We can discuss our options in more details in chat if you are interested in my offer. Looking ahead for a great experience working together! With regards Viktor
