Roman Vinnik

System Designer and Company Owner

South Africa - Tests: 4

I have been developing software for the last 20 years, starting as a junior programmer in the 90's, and now I own a small IT company. We specialise in developing custom software for business, focusing on financial aspects and process flows. We provide an end-to-end solution, including business analysis, system design and specification, development and implementation. Our core strengths are N-Tier solutions using Microsoft based technologies utilising C#, C#-MVC and MSSQL as our preferred database. For Web and Winforms UI we are utilising the Devexpress framework with which we are expert users. We also have competencies in Java SE, Delphi, VB6, VB.Net , MySQL and others. We do not develop new projects in these technologies but have the know-how and experience to migrate from them, or integrate to them. My time right now is limited. I am available for a free 1 hour consultation, after which planning needs to take place and my time becomes billable.

Bojan Gavrilovic



I've started working originally with programming languages Basic, Fortran, Pascal, and C++. However, from the mid 1990s, I've decided to focus solely on Delphi and C++ Delphi versions that I'm using are Delphi 5-Delphi xe7.

I use UML when developing software - ModelMaker or StarUML. I know quite well internet protocols and OpenGL. In the past, I worked on developing passthru drivers, process, thread, image monitoring, virtual printer...
