I'm offering to fully Develop your applications in my familiar programming languages, I can do other languages but that would have to be communicated and client would have to be understanding of the language not being my area of expertise.

1 - Client buys service

2 - I reach out to client and request information

3 - Client sends information and any documents I ask for which could include a description of functionality to design files from figma or any other design tool that can be converted to code.

4 - I send the client my completion time, and update client daily on progress with images.
