About
Matias has spent nine years building in game engines, real-time graphics, multiplayer systems, and, most recently, in-product AI. He is known for taking on complex engineering challenges, such as architecting the deterministic multiplayer of a VR title and shipping it across five platforms from one codebase. Earlier in his career, Matias co-founded a small studio, leading engineering efforts to deliver five distinct products. His range includes tackling situations with no clear path forward. One memorable project involved porting a Flash game to a new stack without documentation or a Game Design Document, requiring him to reverse engineer a server from its responses. This deep technical curiosity extends to his personal projects, where he's developing Kooch, a GPU-driven engine in Rust, and Elal, an AI coding agent, both publicly available. Matias thrives in environments where technical performance is a core requirement, not just a bonus. He seeks to work with teams that prioritize the product and respect well-reasoned technical decisions.
Highlights
- Shipped a deterministic multiplayer VR title across five platforms from a single codebase, holding its frame target inside strict frame-time and battery budgets on standalone headsets.
- Reverse-engineered a legacy Flash game server from its responses alone - no source, no documentation, no design doc - and ported the game to a new stack.
