Sergey Dvoynikov - Resume

Foreword

I am 40 years old, married, have a daughter, and currently living in Novi Sad, Serbia. I am looking for a local/remote job or relocation opportunities.

I have been programming since 2004 (professionally since 2007) and have a broad background across various technology stacks. I have experience in team leadership, project management, and software architecture. I have worked on numerous projects from scratch to release and beyond, both independently and as a member (and leader) of a team. I have maintained and improved legacy codebases, as well as designed new architecture solutions. I am a team player, a fast learner, and can quickly adapt to new technologies. I am always seeking new challenges and opportunities to grow.

Experience (long)

C / C++

• 2005-2008 Learned programming concepts and honed skills, working on creating games and game engines.
• 2011 Spent some time programming in Objective-C for iPads.
• 2023-2024 As part of developing my own scripting language “Nar”, I wrote its virtual machine in plain C.
• 2025-2026 Working on the database engine for Microsoft Azure, writing code in C++.

Rendering

• 2005-2007 While building a game engine, learned OpenGL (version 2) and DirectX (versions 7 and 9), diving into the rendering pipeline and shaders.
• 2022 Learned the Vulkan API and wrote a simple renderer using it.
• 2023 Experimented with different rendering techniques, writing a game engine using WebGPU.

Java

• 2008-2009 Developed multiplayer(!) games for cellphones using J2ME and Java 1.3 for backend.
• 2010-2014 Worked on a large outsourced project for IBM, developing an Eclipse-based application in Java 5 designed for building dashboards for database analytics.

Flash / Actionscript (RIP)

• 2011-2013 Experimented with Flash and ActionScript to create games, releasing a couple on ArmorGames and Kongregate.

Python + Django

• 2013-2014 Learned Python and Django while working on personal projects, developing small web-based applications.

Javascript + TypeScript, React, Node.js

• 2014-2016 Worked at a startup, leading a team of developers to build a web-based application using React (starting with version 0.9) and TypeScript (starting with version 1.0). The project was a platform for building dashboards (similar to a form builder) for analytics. I also worked on a few other web applications.
• 2017-2018 Developed several personal projects using the web stack, both front-end and back-end. One of these was a collection of themes for JetBrains IDEs generated online based on color palettes (now closed :( ).

Go

• 2014-2024 I'm very passionate about the Go language. I started using it with its early beta versions and now use it wherever possible (and sometimes where it's not!). I’ve written many server-side services using Go, developed a compiler for my scripting language “Nar” using pure go, and experimented with creating games using the Ebiten engine and Vulkan bindings.

C# / Unity

• 2006-2024 Started using C# back in version 2 and have used it for many different purposes since.
• 2016-2024 Released three major PC games—Train Valley, Train Valley 2 and Train Valley World—along with DLCs. Worked on many prototypes and personal projects, diving deep into Unity3D and C#. I've worked extensively with shaders, DOTS, Jobs, and Burst, developed custom terrains, built my own ECS systems, created a multiplayer synchronization layer, wrote multithreaded code, and performed a lot of profiling and optimizations.
• 2025-2026 Working on the database engine for Microsoft Azure, writing support/testing code in C#.

Afterword

My passion is game engine development. I have been building my own game engines for a long time, experimenting with different rendering techniques, physics, and networking, and trying out various approaches, techniques, and languages.

One of the most challenging tasks for me recently was developing a programming language. There is currently no declarative functional scripting language, so I decided to make something like Lua, but with a Haskell approach. It was a fascinating and challenging task, but in the end I designed the language and wrote a compiler (in Go), two virtual machines (in C and Javascript), a wrapper for use in .Net (in C#), the main library of functions (in Nar itself), a language server protocol implementation, and a plugin for integration into Visual Studio Code. To do this, I had to apply many different technologies and study fundamental scientific works on how compilers work. The language is fully functional, but not yet in a release state, as it still requires some polishing and documentation. All the source code is available at github.com/orgs/nar-lang/repositories. Later I reworked it to run on top of the Lua VM to benefit from its widely used ecosystem and libraries.

I keep up with modern trends and actively incorporate AI into my development workflow to speed up delivery and make the resulting code more robust. I use AI-assisted tools for prototyping, code review, refactoring, and testing, while keeping a critical eye on quality and correctness.

I have a strong desire to create something new and unique, and I am always looking for new challenges and opportunities to grow.
