Write technical report on a SaaS that's already built

I need a technical project report for a SaaS that's already been built. The report should have a literature review, system analysis, system design, methodology (I'll provide the technical stages of the project), conclusion and some references.

The project is a payment system that's built on emerging technologies like A.I and blockchain, so some research should go into researching those two subject areas.

Additional details will be provided upon engagement
