Gabriel’s fiery passion for performance means he’s probably the only guy who thinks 2.5 frames per second is a polite conversation starter and that walking simulators are just elaborate excuses to not finish a game.

Secured corporate clients for his 3D engine purely based on its remarkable speed—10x faster than Unity with instant loading on constrained platforms—demonstrating that his innovations aren’t just theoretical but commercially viable.

To revolutionize game engine technology by creating tools that drastically enhance performance and efficiency, empowering developers to build richer, faster, and more immersive gaming experiences.

Gabriel believes that speed and efficiency in software are paramount and that current industry standards often fall short. He places a high value on practical optimization over hype, authenticity in game development, and the pursuit of relentless improvement in code performance.

Exceptional technical mastery in low-level programming, the ability to innovate rapidly with tangible, high-impact results, and a public presence that highlights the importance of performance in gaming software.

Gabriel’s blunt, sometimes sarcastic tone may alienate those less technically minded or those sensitive to his no-frills style of criticism, potentially limiting his appeal outside hardcore tech audiences.

Gabriel should lean into Twitter threads that break down complex engine optimizations in digestible parts, using eye-catching benchmarks and video demos. Engaging with broader game development communities by demystifying tech jargon can expand his reach beyond hardcore programmers to indie developers and enthusiasts seeking technical insight.

Gabriel’s animation system coded in pure C runs 14 times faster than Unity’s animation system, all while needing no further optimization—talk about speed without the sweat!

just finished my animation system in C and turns out it's ~14 times faster than @unity's animation system. I didn't optimize any of this btw, probably could be much faster still 🧵

every time I talk about my engine with devs that used @unity their whole life I always get the same reaction: 1 - they don't believe one person can build an engine that surpasses it and 2 - even if they could, it must result in tech that is "too hard" to use this used to bother me a lot, but today I realized something 🧵

a lot of people didn’t seem to believe that my C engine is 14x faster than @unity on the web. so I made the demo available online, link in the 🧵 the Unity project is on github, I’m still on the fence whether I’ll post the C code or not, maybe under CC non-commercial?

for anyone with high enough attention span, I just re-watched 2 lectures by @cmuratori which I believe are probably the best educational content on Software Architecture out there. (and it's freely available) In order, they are 🧵
