Full-stack development of payment processing system (database, API, front-end)

Starting to work in this company, I decided to improve my skill in the database development. Also, I was interested in web-applications to make web-base clients for my databases. Now I'm administering multiple databases on multiple MS SQL Server servers and develop different web-applications, using Microsoft ASP.NET MVC.

It was the most boring job, I ever had! I was there doing nothing.

This is renamed B-Systems company, so my activity there was the same. Only job title was changed.

During this period I moved from the database programming to the telephony systems. I completed several trainings and began to set up enterprise level PBX's of AVAYA and Alcatel-Lucent.

In this company I created my first database based application. It was Consumers Gas Control Devices accounting system with a Microsoft SQL Server 2000 database and a client, written on Borland Delphi 7.0. I don't know the current situation, but in 2014 an employee of this company called me to know the password from the server and I was very surprised to know that the application still works.

It was my first job. I maintained company's LAN, consisted of several computers, Daemon mail server, ISP connection and office equipment, like printers, scanners, projectors, etc.
