Dear client,
I have worked with Amazon API, both product advertising API and the Amazon MWS API. I know how to pull the product details, and upload the product listings. I have not worked with ebay though, but I can figure out and work with ebay as well. As you mentioned, I will make neat dashboard with modern look. If interested, let us discuss further.
about me:
I am a rockstar web developer with over 10 years of experience in building web applications front end technologies like JavaScript, Angular 1.+, Angular 5/6, TypeScript, jQuery, HTML, CSS, BreezeJS. I also worked in the backend and I am good in the technologies like PHP, MySQL, ASP.NET MVC, ASP.NET Web forms, Web API, Entity Framework, SQL Server.
I have solved several complex problems both in the frontend and the backend, but mostly in the backend especially in C# and SQL Server. I wrote several procedures, triggers to accomplish what the client wanted and also improved the performance of many stored procedures.
