Sebastian Janisz

Sebastian has over a decade of programming experience in games and tech.

As a programmer for Interactive Projection USA:

• Created OpenCV algorithms from scratch for interactive projection screens. 
• Managed a subcontractor to make interactive Unity-based demos to be run on projector/IR camera setups.

As a programmer for ilovecreatives:

• Developed a flashy, interactive online class styled as a "point and click" game. 
• Worked as the sole programmer for both frontend and backend. Frontend was developed with Pixi.JS, and backend uses Node.js and Auth0.

As a programmer for Hutch:

• Developed a complete AAA-caliber frontend for a mobile game; worked as the only coder for the frontend.
• Built the project in Unity, making heavy use of Unity UI, shaders, Asset Bundles, and editor tools. Project communicated with a web backend that was simultaneously developed by a team.

As a programmer for AiR Everywhere:

• Established sophisticated AR/GPS tracking software which used custom algorithms to outperform the system hardware. Built with Swift, Unity, and ARKit.

As a programmer for Octi Inc:

• Created a prototype augmented reality app from scratch in Unity, which interfaced with an existing RESTful web API.

As a programmer for Snowman:

• Performed maintenance on the hit mobile game, Alto's Adventure.
• Added a screen-recording functionality and UI to the game.
• Tracked down crashes that were happening only on older devices, by debugging through Xcode.
• Performed exhaustive on-device optimization through the use of Unity's profiler and other strategies.
• Helped with Apple TV compatibility.
• Implemented a Zen Mode game type and utilized technologies including Unity3D, C#, Xcode, and Objective-C.

• Invented a patented tracking algorithm during the development of Star Wars Jedi Challenges AR, which uses only a phone as the hardware, a feat other experts claimed was impossible.
• Trusted with high-priority R&D projects that other programmers couldn't solve, most of which involved augmented reality.
• Created low-level Unity3D Android plugins to facilitate AR tech.
• Developed 4-dimensional linear algebra equations and other math to facilitate AR-tracking and solve other problems.
• Wrote a highly optimized C# code to extend OpenCV's capabilities and interactive AR demos in raw Java using OpenGL ES.
• Developed flashy demos, with liberal use of shaders and particle effects, and interactive characters, to be shown to Disney executives.
• Managed mechanical engineering work creating simple working AR tech prototypes.
• Worked with mechanical engineers to ensure their prototypes met the technical requirements for the AR software to work.
• Helped with rapid prototyping of toys and games, and maintenance of the Playmation mobile app.
• Used technologies such as Unity3D, Unity3D Native Plugin Interface, OpenGL ES, OpenCV, Vuforia, C#, C++, Java, Python, GLSL, ShaderLab, NGUI, Android Studio, and AR/VR.

Vertalex is a video game studio that develops experiences for mobile platforms.

• Managed a small team of programmers for a mobile Unity game remotely.
• Developed a custom collision detection system using quadtrees, which fit the game better than Unity's default collision detection.
• Wrote custom scripts for sprite rendering, which at the time, outperformed both TK2D and Unity's native sprite rendering.
• Created custom soft-body physics for the main character.
• Developed a random level generation system.
• Built various flashy visuals and particle effects and utilized Unity 3D platform.

Sebastian worked on the high-profile iOS game, Where's My Water?.

• Handled and was in charge of implementing new mechanics, including y-switches, mud, and mystery ducks.
• Single-handedly designed and implemented the mud game mechanics.
• Participated in much of the game's design. Attended all game design meetings.
• Contributed to many levels to the game; eventually preferred designer for harder levels involving more difficult puzzles such as Gravity Dynamo.
• Designed and wrote the programming for the successful spinoff, Where's My Perry?, from conception to release.
• Developed programming work that was primarily on a proprietary C++ based engine.
• Used technologies such as C++, Photoshop, and Proprietary Engine.
