This is not a complete list of my skills. Some I use often, and some not very often.

I worked as a C++ and Python developer on the development of p2p technologies based on the STUN protocol. Built LUA
support into the project. Was responsible for the development of the Rest API for server/client communication. Created a
streaming system for transferring large files.

The work was very varied.

Initially, I was a developer. Created basic mechanics for a character in C++ using Logic Driver, GAS Companion and some additional plugins.

Later, I also worked on the development of the procedural world, partly with technologies from the demo version of the matrix ( Unreal Engine 5 ), and also used Houdini to create my own tools.

In parallel, of course, I also supervised a team of young professionals.

In addition, I had to maintain a system that I developed myself on submodules (GIT). I got acquainted with the TeamCity server (JetBrains), before and now I used only Jenkins.

During the whole period I learned a lot of new things and it was a good experience.

I had to update the entire system of the demo “SimpleCity” in Houdini and UE to version 5.1, since the entire project was at that time under 5.0 early access.

Although I worked directly for Cosmos Heroes, in truth I worked with a subcontractor. Cool dude named Robin. As a matter of fact, when I came, many people were already working on the project. You could even say I was the last one. Since most of the tasks have already been snapped up, I took up the development of a part of the MMO (Photon Engine). Since I worked very often with network technologies before but in a different field, for me it was not a problem and a new experience. I learned a lot here because it was my first official Game Dev job.

PS. Here I first heard the name “danmu” – I had to quickly throw this thing with Robin for a virtual concert in Singapore, for a presentation.

The time was great!

I delved into the insides, I’m a C ++ developer after all. I made videos on my YouTube channel, worked here and there. Overall I took a long vacation.

I was engaged in the development of a ready-made server system and tools for diagnosing hardware under Windows and Linux.
I also developed ready-made solutions for Android on Android Studio.

Over the years, I have learned a lot of technologies, both in the field of electronics and in the field of low-level programming.

In more detail, I was engaged in both Backend and Frontend development.

The server part was written by me as a set of microservices (about twelve in my opinion) on the Django REST API technology and then rewritten for Blacksheep.

I have used technologies such as RedisDB for hashing and fast accessibility of elements. MariaDB (SQL) databases for long term storage. RabbitMQ (MQTT) for asynchronous data transfer between microservices over a multi-level system of message importance.

There were several client software parts.

The most important is the SDK itself, which was written cross-platform in C++/Assembler using LUA.

The client part of the program under Windows PE was also written with the SDK, booting under the BIOS and UEFI systems.

Under the Linux version, its own OS was developed based on Slax / Portues and the client part of the program was adapted for it.

Web interface for access to clients, administrators, technical support. It was written in Django, jQuery, JS, CSS and HTML.

The Android application was written in Java (Android Studio). First as a WebApp, and then completely made in Java.

All client parts were secured via IP logging / JWT / OAuth2 and techniques I don’t remember anymore.

The SDK had a lot of features for determining hardware parameters, status, and discovering new devices.

In general, this entire system could not only carry out hardware diagnostics, but, in fact, reinstall Windows / Linux remotely.
In addition, access to the computer was enough from a regular phone (though only Android).

…now the system is either under development or already abandoned.
