I have developed a tool using Excel for Economic Feasibility Analisys in Energy Projects (Cash flow, irr, npv, payback, sensibility analisys ...)
Now, I want to develop a similar tool but using PowerBI + DAX to make it available online for my customers, where they can change some inputs manually and get the updated feasibility indicators.

Caros, boa noite,

Nosso projeto é o desenvolvimento de um APP em flutter ou alguma outra tecnologia que seja possível obter acesso aos recursos nativos dos dispositivos móveis como câmera, leitor facial ou outros.

Phase 1

Below we describe the app's basic information and log in process:

app's name: isp24
environment to be used: we're a tech company in brazil that offers solutions to isps (internet service provider) in a b2b model. In case, our customers should be the ISP, and they should provide through this app services to their customers in a B2C model;
Goal:  ISP's customers should execute/request some services on the app;
Authentication - users should be able to log in using a document and their birthdate or phone number; if the app recognizes the document entered by the user in the contract's table, the user can choose between google or facebook to login easily next time.
After the log in, users should select the contract, because a user could have multiple contracts;
Based on the contract, an isp custom logo should be shown to the user and the isp details such as name, address, phone number.
We are going to provide each api returning json with the data to be handled in the app.
We are going to provide some mockups showing what we expect of each screen. 


Below we describe each service that should be available to the customers in the app channel after user login, following their priority. We describe each requirement specifying how it should work:

Sign a contract - user should be able to open a pdf linked to his contract, read it and sign the document in each page. The app should get the operation's datetime, gps position and should request a photo of the user signing the pdf. All this data should be sent to a server to be stored in our database;
Request a financial invoice - users should be able to see their financial invoices, choose one and get the barcode or qr code to pay it. For now, we don't need credit card payments;
Reset their connection - this is a screen where users could reset their connections when they are facing connection issues. Basically, it needs to execute a url script on our server, but users should be able to follow the process through the app.

I need to finish the development of an application for the general public, where musical services will be contracted.

The application is developed in Framework7 – Cordova language and will be published for iOS and Android. The APIs are completed and developed in .NET. The application layout is done and it is necessary to integrate screens with the API.

It is estimated the integration of 8 screens

Some features of the app are: payment gateway, image inclusion, geolocation, user rating and push notification.

The developer needs to be an expert in Framework7 (Cordova).

The presentation of a portfolio with emphasis on the mentioned resources will be a differential

The frontend developer will have contact with the project's business analyst and the API developer to clarify doubts.

The main proposal for this platform is to receive deliveries from customers with information (Origin, destination, Product, Product Dimension, quantities and route) and optimize thus products load on the trucks respecting the capacities and restrictions according related capacity for each equipment.
Here we need a algorithm that once the deliveries were optimized and allocated on the equipments we need to create a better optimized route considering all routes infomed on the deliveries by the customers.
Is very important to have two options for the Optimization features:
First one is private model that shall consider only deliveries of the same customer.


Second one is share model that shall consider all deliveries for a group of customer that are previouslly set up in the customer master data.
For both cases the suggestion is to use API from Google Maps in order to have the better information regarding to the faster and low cost route, providing to the customer operations the best option . Generating ETA ( Estimated Time Arrival) to each stop delivery inside the routes in order to tracking the deliveries in real time and take decisions in case some of then got a delay or any other issue during the process.
The feature that we suggest to execute the real time tracking is to assign the truck driver mobile phone to each load which is performed and monitoring just during the travel time, from Arrived in the Plant  to the last customer or final destination defined in the route optimized.


The last requirement is to have a BI solution in order to create some daily, weekly and monthly standard reports to driver the customers.
