Hello,
I'd like to help you on this! I understand the posting of the products (or any data) is failing due to the high number of records being posted at the same time (within the same call). I will analyse the current method and sources and make recommendation then implement the best way to reliably and most efficiently transfer any number of records - in batches preferrably. I will modify both client and server-side as necessary, test and document changes. My bid is for this modification, for the follow-up works mentioned in the project descripton I will quote time and cost separately once the requirements have been understood sufficiently.
About: I freelance next to a dayjob (leading a development team of 10, working on a bespoke ERP - .net/MSSQL based - for a major automotive company) and in my freelance life have completed hundreads of projects working mostly with the Microsoft technology stack. I have a vast experience with .net/SQL development ranging with desktop (WinForms, WPF), server-side (SQL, ASP.Net/WebForms, MVC, WCF), multi-threading, etc. I'm committed to delivering value, efficiency and transparency.
I look forward to discussing the next steps with you.
thanks & regards,
Janos
