Hey! My name is
Donatas Mockus
Game Developer \\ Full-stack Web Developer \\ Software Engineer
[briefly] about me.
Hi! My name is Donatas Mockus and I'm a software developer from Lithuania. I started my programming journey at the age of 13, making simple 2D platformers in Unity using C# and JavaScript (remember when that was in Unity?!). At the same time I took interest in programming in general, exploring languages like Ruby (which I swore I'd never use again), C++, HTML, and CSS.
Today I am primarily a professional C++ developer. I spend most of my time developing video games using Unreal Engine 5 but also delve into other paradigms such as web development, compiler design, and embedded programming.
Thank you, I spent 10 whole minutes animating this button, so I appreciate your interest!
In my mid-teens I got tired of programming and started exploring different hobbies. I started out with graphic design creating logos for myself and friends. That led to an interest in 3D modeling; I used to make abstract renders I'd post to Instagram. Eventually I started drawing, mostly some wacky abstract sketches but I have created a couple of murals too.
All of this eventually came full circle when I took an interest in cryptography and netsec. I quickly realised how valuable programming was to these activities and decided to get back into it, however, I quickly grew tired of making ultimately pointless applications on my own and so when I turned 16 or 17 I wanted to collaborate with someone. I often say that I didn't choose game development, rather it chose me and that's exactly what happened - I was asked to work on an RPG called Growth of Glia. We made some nice progress and that project made me interested in project management. I had the privilege to lead a small team of artists, writers, and composers. Glia was a passion project for us and many of us were still teenagers trying to bring our ideas to life, but that was a lot more difficult than we imagined. Passion fizzled out and I started to look for something new. That's how I found Virtuverse.
Virtuverse without a doubt had the biggest impact of my life. I started out as a gameplay developer fixing some bugs and it snowballed into me managing the project, attending Sweden Game Arena and GDC, and moving to Sweden. In our first three years we released six major updates, built a passionate and supportive community, and built a game I'm genuinely proud of.
While programming is still my primary hobby (and day-job!), I maintain an interest in a great number of subjects such as digital electronics, music, chemistry, photography, woodworking, knitting, baking, gardening, and many more. Even within computer science I enjoy working on a variety of areas beyond games like compiler design, open source software, system administration, UI/UX design, performance critical application development... Honestly, if I had to list it all, I'd have to update this website monthly!

Virtuverse
Virtuverse is an RCE MMO-RPG set in a virtual world. A sort of sandbox-on-rails, Virtuverse allows players to specialise in different professions: crafting, mining, hunting, and many more; go on quests, ally or fight different factions, and explore the large and open worlds. I have worked on Virtuverse for more than four years along with a team of extremely talented developers and artists. Over the course of these four years, we have shipped more than 6 major updates and are currently working on the 7th, which is a complete rewrite in Unreal Engine 5.
The artwork you see here is done by the amazing Keegan Blazey.
