Build a Saas project with web & mobile apps running with Azure

We need a software developmment team with high skills and experience with Azure. It's very important to show us similar Saas projects created by the team with Azure enviroment. Here is our project description:

SmarTax is a SaaS solution for accounting and finance targeted at self-employed individuals and small businesses. This intelligent software employs a chatbot based on OpenAI GPT-3, which allows interaction with the system through voice or text commands. The user can request the generation and sending of invoices, extraction of accounting balances, tax planning, and development of investment strategies. It also allows the automatic creation of quarterly and annual tax drafts, which can be submitted after their approval. The scanning functionality enables automatic accounting of food and fuel expenses. SmarTax synchronizes banking movements with the user's accounting through integration with banking entities. Furthermore, it manages labor aspects such as hiring workers and sending monthly payrolls. All of this is complemented with a 24/7 tax, labor, and accounting advisory service. Built on Microsoft Azure, SmarTax is a secure, efficient, and user-friendly system that offers an all-in-one solution for accounting management of self-employed individuals and small businesses.

We will share a complete briefing in private chat discussions. Please note that we already have the full UI screens kit made for web and for mobile apps in dark and light versions.

So we need to create landing page from existing coded template and do all backend of the project and front end using our UI already made.

We share a couple of UI screens.
