About Me
I first became interested in computer technology in 1996, when my parents got a computer based on Intel Pentium 100 MHz and 16 MB of RAM,
then there was MS DOS and Norton Commander, then Windows 3.11 and finally Windows 95. I was interested in exploring each new system or program,
editing and setting up configuration files, later, when the power of my computer was not enough, I had to overclock the computer processor to 150 MHz, so I acquired a new hobby "Overclocking",
and also to support new computer games, manually integrate the libraries of the new API DirectX 8.1 into the Windows 95 system, which was not installed out of the box, since the new at that time Windows 98 consumed
significantly more resources! Around 2000, when many free hosting sites and guest books appeared, I began to independently study
HTML and CSS, the result was an author's site with maps and replays for the popular computer game StarCraft at that time in a design borrowed from the game interface.
In 2002, my friends and I organized a local network in our yard (15 computers), later I wrote a messenger in Delphi 7 that allowed exchanging
messages and files between users of our local network.
After finishing school, I entered the "Immanuel Kant Baltic Federal University" (former KSU) in the department of "applied mathematics and computer science" in the specialty "mathematician, system programmer"
In 2006, I developed the first parser of product characteristics for an online store (Office Express), which removed unnecessary layout and HTML tags, leaving only what was required for the site of the online store (CMS Westpower).
The parser for the online store was written in Delphi 7. At that time, my responsibilities included: translating and publishing articles from foreign sites,
updating the product catalog, filling in technical specifications of products, later I began my acquaintance with PHP and JavaScript.
For the online store (Office Express), a "computer designer" was made with a check for the compatibility of components (PHP, JS, Ajax, MySQL).
After completing my studies at the university, and a brilliant defense of my diploma on the topic "Computing on graphic processors (Nvidia CUDA)"
I got my first serious job at a large financial company InstaForex, where I gained a huge experience in developing on PHP and MVC frameworks.
After some time, I went freelance, in the process of working as a freelancer I gained a lot of experience in developing on CMS: ModX, 1C-Bitrix, Umi, Wordpress, but having earned enough money, I returned to product development again, since the tasks on a freelance were mostly typical and uninteresting, there was a feeling that I was professionally degrading...
