Work Experience
Unity Developer
2024 - 2025
mlxar GmbH d.b.a. Atlas
- Implemented a Render Graph version of the rendering pass for Universal Render Pipeline and added the shadow feature using a convex hull algorithm for approximating the volume of Gaussian splats.
- Developed a mesh conversion editor along with supporting GUI utilities, added a mesh texture extractor postprocessor, and fixed key issues such as PLY vertex stride and Z-axis flipping.
- Enhanced the editor integration by adding support for Editor Coroutines and improving error handling for insecure connections. Polished the asset creation process and ensured cleaner file path handling.

2024 - 2025
mlxar GmbH dba Atlas
- Developed interface for client's plugin to send prompts for AI generation to the back-end server, track the status of the request, and process the response to create Gaussian splat object.
- Implemented the required structure to conform to Unity's standards to release the plugin as a verified solution and Asset store package.
- Implemented support for Built-in, URP, and HDRP rendering pipelines on Unity 6 and earlier editor versions.
- Adapted implementation of custom rendering pass to integrate with the latest rendering graph API introduced in Unity 6 as a new recommended standard.

Hockey Manager
Front-end and back-end developer on a hockey manager game project for desktop.
Trillenium
Early development of a prototype for a 3D retail store based on a 3rd-person view and interactions with store items within a virtual mall. The project consisted of implementing dynamic store areas, entertaining games, and improving the visuals of the environment. To import real products as virtual store items, a unique hardware setup was developed to scan the items on a rotatable table with a combination of high-quality digital cameras and depth sensors from the Kinect device.
Runner Runner Poker
This was a project for an iOS poker game prototype with unique touch gestures. We've built a cloud-service-driven game using Microsoft Azure and PubNub networking. We've also built a game with Unity and integrated Facebook login, friends lists, and in-app purchases.
