Work Experience

Founder, Lead Developer

2018 - PRESENT
  • Created an online co-op first-person horde shooter using the Unity engine (HDRP).
  • Developed gameplay logic and systems that are fully replicated over the network.
  • Designed enemy AI that focuses on surrounding and flanking the player, enhancing the active and fast gameplay experience.
  • Built fast and efficient networked transforms that performed around 10-100 times better than the default Unity implementation at the time and allowed us to have 30 moving enemies on-screen at the same time.
  • Developed a high-score system integrated with a discord bot, providing real-time updates to discord members when new records are set on a given day.
  • Ported many visual effects from the standard rendering pipeline and URP to HDRP.

2017 - 2020
  • Built a smart office platform for the Mapiq platform, used to manage many office features, such as meeting room availability, colleague localization, and integrations with numerous IoT devices and business applications.
  • Developed the back-end architecture used for most microservices and the Mapiq OfficeShifts product.
  • Developed parts of the localization framework used to show the position of employees within a building via routers and a smartphone app.
  • Designed a microservices architecture to replace the legacy monolithic server architecture.
  • Assisted in the development and migration from a single-tenant to a multi-tenant application, removing the need for individual servers for each tenant.
  • Redesigned and developed a new setting layer to replace an old settings layer that had not performed as intended. The performance gain was a few orders of magnitude faster.
  • Spearheaded code quality improvements, such as introducing SonarCloud, style guides, StyleCop, test coverage gates, and code reports. These changes improved the future development speed and code quality.
  • Designed several CI/CD pipelines within Azure DevOps. Some of these pipelines were used to publish internal packages, and others were deployed to the Mapiq platform.

  • Developed parts of the PSA project management suite and assisted in porting the old Microsoft Silverlight application to HTML5 using Ext JS.
  • Built a tablet/phone app for Windows Phone using URP and .NET. The app showed project details in a quick and organized way.
  • Developed a financial accounting suite for the company.
  • Published and maintained apps in the windows store.
Technologies: C#, .NET, HTML5, Ext JS, Microsoft Dynamics CRM, SQL, SOAP, SoapUI, Subversion (SVN)

Mapiq Office Shifts

A workplace reservations app that was developed when COVID-19 started. I did a large part of the back-end API development, and we created the first version in less than six weeks. By the time I left Mapiq, employees could not only reserve workplaces for a given day but also parking lots.

An online co-op first-person horde shooter that's currently in development at my studio. I've done a lot on this project, from game design to netcode and everything in between. The game is built in HDRP and can hit 60fps on an RTX 1050 Ti.
