Hi, I'm a software engineer with over 10 years of experience. I've worked across very different industries and technologies, and I adapt to new ones with ease.

My background spans .NET enterprise platforms, VR training apps, and casino game backend services and frontend prototypes. I'm happy joining big teams and working with huge, complex legacy systems, but what I enjoy most is building things from scratch.

In my free time, I make game prototypes in Unity and C# with friends at game jams and hackathons. In 2025 I built a series of Meta Horizon Worlds games - and won a few competitions along the way.

Experience

Full-stack Developer, Nailed It! Games

11.2025 - present (10 months)

A full-stack role, mostly backend. I work on the .NET/C# backend, and build frontend prototypes in HTML and JavaScript. This is my first job where I use Cursor and Claude on a daily basis.


Projects:

  • Riptide Pirates 3 - built the backend based on the previous game, created the frontend prototype from scratch, and focused heavily on performance optimization, profiling and resolving bottlenecks with the Rider Profiler

Advanced Software Engineer, Relativity

08.2024 - 10.2025 (1 year)

I contributed to a .NET-based eDiscovery platform as part of the backend development team. Within the Processing team, I developed and maintained services responsible for processing files.

  • Delivered new features, resolved issues, and enhanced system architecture
  • Stack: .NET, Azure, MS SQL, Temporal, and more

Software Engineer, Sim Factor

10.2021 - 07.2024 (3 years)

Developed VR training games for standalone VR headsets, from game mechanics design to server-side communication.

  • Vectron machine room - VR frontend for a full-cabin simulator
  • CityJet - VR frontend for a full-cabin simulator
  • High voltage pole grounding - standalone VR training game
  • Intercity elevator - standalone VR training game

Designed a reusable VR framework for future projects:

  • Set of common reusable VR objects and mechanics
  • Multiplayer support to synchronize states between many players, utilizing a central server created with Blazor and SignalR
  • Framework was adopted successfully by other developers

Optimizing VR projects:

  • Identifying and resolving performance bottlenecks
  • Collaborated closely with 3D artists to deliver optimized assets
  • Utilized game-dev tricks to enhance performance and visual realism

Worked in a small (2) and bigger (7) team:

  • For VR applications I was fully responsible for the entire project, working with one or more 3D artists
  • Contributed to other projects by completing specific tasks, such as creating a frontend for a warehouse simulator within a larger solution

Planned, estimated costs and managed projects:

  • Created estimates for future projects
  • Planned tasks for upcoming sprints
  • Participated in client meetings
  • Demonstrated ability to stay steady during challenging client interactions, earning management recognition

Prototype Developer, Yggdrasil Gaming

08.2019 - 09.2021 (2 years)

Produced high quality prototypes of new casino games. My goal was to show how a new game idea works in real life before it gets to the production team. Worked mostly with C#, Unity UI and DOTween.

Programming Teacher for children and youth, Giganci Programowania

09.2019 - 01.2020 (5 months)

A side job alongside my main role. Taught basics of programming and computer security to students aged 9-15.

Intern → Software Engineer, Nokia

08.2015 - 07.2019 (4 years)

As my main task was to develop and maintain a mature product (a suite for 3rd generation mobile network monitoring), I took the opportunity to gain broad exposure across many areas. Looking back, I realize it was a valuable starting point for my career as a software engineer.

Some of the things I did:

  • Working with legacy code, fixing bugs, applying security fixes, writing technical documentation
  • Writing new code in Python, Bash, Perl, some C++
  • Leading SCM team and maintaining product delivery to the client
  • Automating manual procedures using Python, Bash, Perl and Jenkins
  • Work with various operating systems: Windows 10, Solaris, Windows Server
  • Work with various software: PyCharm, Visual Studio 2017, GitLab, Jenkins, ClearCase, Jira
