As a technical game designer on the LoL Game Modes team, I got the chance to work on Ultimate Spellbook, ARAM's 2022 pre-season update, and designed the map layouts, juices, and introduced the deep water terrain type to LoL and created the Power Flower for Arena. I was also the sole game designer for the Nexus Blitz 2023 revival and the 2024 URF Lunar New Year release. On the technical side of things, I served as our Subject Matter Expert for map editing, acting as consultant on several tool updates, including grayboxing and character creation. I also did engineering work to update the Event UI to modern standards for Nexus Blitz. For Arena, I helped pioneer the use of our map-within-a-map system that had previously only been used in TFT and used it to set up the different game arenas.

Through my time as a tools & pipeline tech artist at Riot, I supported 3D artists, tracked and optimized our memory usage for our game modes, integrated VFX, updated several core outdated rigs and models for LoL as a whole, and laid the groundwork for improvements to our map editing toolset.

As tactics supervisor, I led a 4 man team whose goal was to look for inefficiencies within our film making process and search for holistic solutions, as well as to monitor render times and identify any potential outliers. This process was a studio wide collaborative process, and led to the creation of a tool that connected ShotGrid data to our final images to allow artists more convenient access to their shot status, using stereo masks to reduce the amount needed for stereo renders, drastically reducing render times for applicable shots (saving up to 90% of render time in extreme cases), new tech check processes for character asset review that reduced errors downstream, and more.

As a technical director at Disney Animation, I primarily supported our lighting, crowds, and animation departments, and became one of our department experts on render optimization. Some of my highlights from this period include the creation of an autoculling tool that continues to be run on every movie since Big Hero 6, saving us countless hours of render time, a shader plugin that allowed us to animate region gradients in our renderer, and co-created a graph editor Maya plugin called Geppetto that gave animators the ability to do key cleanup, and manipulate multiple keys across multiple selected curves at a time.
