I had long-term projects for the following clients: Boeing, DHL, NES Corporation, KPMG. Business domains: Accounting, Logistic, Finance.

In all projects, I have close communication with a client to identify functional and non-functional requirements. Some of my projects are:

  1. Boeing.

1.1. The tool to track and manage suppliers’ information.

1.2. ERP system of assembling electronic systems of airplanes.

  1. DHL. The system to manage contracts and calculate delivery prices in different currencies.

  2. NES Corporation. The system to communicate with and setup different electric meters, collect data from them, make reports and charts.
