Work Experience
Founder, Lead Developer
BulletWhale
- 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.
Developer
Mapiq
- 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.
Student Mentor
Technical University Delft
- Counseled first-year computer science students to assist them in the change between high school and university and help them with their homework and other challenges.
- Educated students in software development, source control, and some programming patterns.
- Mediated between students and teachers in quarterly meetings where the performance of students and teachers was evaluated.
Junior Developer
Assistance Software (Acquired by Unit4)
- Built many web apps used within the PSA solution for Microsoft Dynamics CRM. The company was quite successful and later acquired by Unit4.
- 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.
