Hi there,
I can help you in upgrading angular app code base from 4.1 to 8.1. I have the necessary skills to complete this project in time and your budget.
I'm a full-stack web developer specializing in .Net Core, Angular, C#, ASP.NET MVC, Entity Framework, LINQ, Web API, WCF, Windows Services, SignalR, Sql Server, Bootstrap, typescript, jquery, javascript, css, etc. And also knowledgeable in version control tools like GIT, VSTS and TFS.
I will work hard and put in extra effort to meet the project deadlines and deliver the product/work with excellent quality.
Please contact me to discuss further your project needs.
