Commercial Super App

I am looking for a professional developer to create a commercial web application for me. The platform for this web application should be based on Linux, and the final delivery of the application should be a web application. No data will need to be collected as part of this project. I am looking for someone highly experienced with creating web applications and has a proven track record – so please provide me with any references or samples of similar work you may have completed in the past. This is a time-sensitive project, and I would like to ensure that the successful applicant can provide me with a high-quality web application within the agreed timeline.
