Write some Software

Job Description:

The project i'm working on is a monitoring system of solar energy stations. we set industrial x86 computers in station to grab inverters' status and statistics by Modbus RTU. I need to grab statistics from inverters in stations and write it to DB. And Front-end with user management can show each station statistics(inverters statistics summary).

I already have an working app written in C++, but i need it to be rewritten to NodeJS in order to extend functionalities easily. And I have an web, php as backend.

What i need you to help me:

1. I have a script written in NodeJS for capturing data from inverters of solar energy station.

The npm module i used now is modbus-serial. I was in trouble because of the design of non-blocking of NodeJS. I would like to have your help to complete whole life cycle of the app.

What it should be implemented:

a. The app run 24/7 since computer boot up. Schedule the app, it's should capture data from 6 am ~ 18 am (GMT+8)

b. It reads config data from database first, then use these data to setup modbus environment

c. Write captured data to database

d. Basically, rewrite the functionalities from C++ to NodeJS

And Another, make a MEAN Stack web app

Basically, rewrite the web with php as backend now to MEAN stack, and adding user, role, management. and fix some math issues for summary of statistics.

P.S. I will offer u the C++ app and web app with php as backend, so if you are good at C++, PHP, NodeJS and MEAN Stack, please contact me.

Færdigheder: C++ Programmering, Node.js, PHP, Software Arkitektur
