Solution for dispatching air conditioning systems. The primary task was to control big amount of large air conditioning devices, store their working data on one workstation under Windows OS for 24/7, keep that data for 3 years and represent historical data by logs, reports and graphs. Most of those devices were able to communicate through RS485 interface using Modbus communication protocol. 
As those devices can be operated with many parameters rich UI with lots of animation and many custom user controls where necessary. For that reason it was a WPF application.
I was hired by bakery startup for front-end development using React.js with Redux to create production management system with planning, scheduling, techmaps and joinposter.com cloud service integration. The task was to develop custom UI based on designer’s specification. Libraries like lodash, moment.js, axios are being used. This is an interesting project which is currently being developed.
  In 2013-th I with one more teammate started to develop a program for dispatching air conditioning systems. The primary task was to control big amount of large air conditioning devices, store their data on one workstation under Windows OS for 24/7, keep that data for 3 years and represent historical data by logs, reports and graphs. Most of those devices were able to communicate through RS485 interface using Modbus communication protocol. 
We started with .NET Framework and C# language. As those devices can be operated with many parameters rich UI with lots of animation and many custom user controls where necessary. For that reason WPF platform was chosen. Also early analysis showed that we will have to deal with quite noticeable (about 1 million, 4 column indexed records per month) amount of data to be stored locally, so MS SQLServer was a durable solution. 
We finished in 10 months. And I’m maintaining this system till now. Obviously it is not a very well built product. But it does it’s job, it’s quite stable and it’s being used in more than 50 large malls in Ukraine. Some screen shots are included.
  System administrator. Maintenance of hardware and mostly MS Windows based software in about 200 machines park controlled by DC, trading equipment, phone station with about 250 consumers, etc.
Professional growth.
