I was brought on by Neuromersiv as the lead software engineer for a VR app project with no other active developers. The company had created a vertical slice prototype, which was a grey-box version of the product, but it needed significant refinement and expansion. Additionally, the project had to comply with the Therapeutic Goods Administration (TGA) requirements, as it was intended for medical use.

After reviewing the prototype and codebase, I identified that the current structure wouldn’t allow for quick content addition or meet the TGA compliance standards. My task was to develop a new framework that would streamline content creation, ensure documentation, support debugging, and enable logging—all crucial for passing TGA testing. The framework also needed to integrate various functionalities like AWS, UI management, scene transitions, environmental objects, NPC dialogue, and a custom haptics device.

Within the first month, I developed a basic version of the framework that addressed these issues. This framework improved content modularity, enhanced debugging and logging for TGA compliance, and made future content additions faster and more efficient. After the framework’s foundation was laid, we brought on another software engineer. Together, over the next two months, we reproduced the initial content and refined the framework further, planning for its second version.

The second version incorporated features to interface with both web and mobile apps. Additionally, we integrated support for a custom-built haptics glove, created by an engineering company, that required interfacing with a specialized Unity library. To streamline the glove’s functionality, we built extensions and shortcuts within the framework for easier integration.

As the project grew, we brought in a third software engineer. This led to the implementation of peer-reviewed code changes for the framework, enforced coding standards (including SOLID principles), and daily stand-ups to improve coordination. We spent the next four months adding new features like interactive water and expanding content. The framework’s architecture supported AWS integration, scene management, environmental elements, and custom haptics feedback patterns.

At the end of the development cycle, we finalized the content and features, sending the project off for TGA testing. The project successfully passed all medical testing requirements and has since been used internationally as a medical device. The framework I developed not only enabled rapid content creation and feature addition but also ensured compliance with medical standards, significantly enhancing the scalability and future-proofing of the VR app.
