Dear client,
I have written crawlers and parsers for several projects. I have used HTML Agility Pack, C# Linq queries, Regular expressions, XPath queries extensively and extracted the required data. If you can give me what sites and the what data points you want to crawl and parse, I can then give you an honest estimate of the cost and time needed.
About me:
I am a rockstar web developer with over 10 years of experience in building web applications using PHP, MySQL, ASP.NET MVC, ASP.NET Web forms, Web API, Entity Framework, SQL Server.
I am also very good in the client side technologies such as JavaScript, Angular 1.+, Angular 5/6, TypeScript, jQuery, HTML, CSS, BreezeJS
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.
