NOTE: I was Top Rated Plus with 100% job completion until my very last short job that didn't work out and She gave me 1 star...But please read all of my reviews to see my history. Hello, my name is Jay. I'm currently living in Tampa Bay, Florida. In 2018 I resigned from a long term, senior development position (10 years total. 9 of which were remote full time, and 1 year working in our Minneapolis office). I decided to move into freelancing and possibly freelance to permanent if I find the right opportunity. Beyond software development, my strengths are: Communication, Finding the Right Business Solutions & Delivering what the Customer and Users Expect. Since beginning software development, I've learned that consistent and clear communication is the main key to success in the completion of software projects. I've worked mostly in eCommerce, credit card processing, payment processing and hardware API integration, mobile Xamarin development, SQL Server programming & database design. Also, recently have completed a large Stripe integration. Most of my work, from a platform standpoint, has been in C#, VB.NET, ASP.NET Core, ASP.NET Web Forms, Blazor, Entity Framework Core & Xamarin. I've completed multiple large software projects on a freelance basis from the ground up. From specifications planning, programming & launching into production. The first of which led to my 10-year role at my previous job after the initial build was complete and in production. Please reach out to discuss your projects!
