Real Estate Website Development

https://apkcombo.com/es/chedueno/com.chedueno.app/
As a solo startup, I created a website similar in functionality to Zillow but only for homeowners to advertise their houses. The idea was to avoid realtors commissions. The site was created using C#, .NET MVC, and Entity Framework. I did all the deployment and hosting using AWS with a virtual environment with Windows servers and SQL. The site was profitable, but I decided to shut it down due to a growing number of fake ads.
