With my extensive background in web development using a diverse set of tools, I believe I am well-suited to create the URL Shortener website you envision. My experience in Python, C# .net, VB.Net, Web API Core, ASP.NET MVC Core and more have enabled me to provide robust solutions to complex problems in the past, and this project will be no different.
Additionally, my proficiency in technologies such as JavaScript, HTML, JQuery and CSS give me an edge when it comes to creating user-friendly interfaces that are intuitive and aesthetically pleasing. I understand the importance of a clean UI for a URL Shortener platform, where users need quick and easy access to functionalities.
In terms of security and administration tasks you require for your site, I have extensive experience working with databases like SQL Server and MongoDB, setting up user workflows, maintaining admin rights, data extraction, sharing metadata - all of which will come handy for implementing user registration with admin approval capabilities on your website. I understand what it takes to build maintainable applications that are adaptive yet robust. Together let's build a platform where every URL gets the treatment it deserves - being fast tracked for redirecting or cleaned out when irrelevant.
