Victor.
M2HCZ / M2HCS
A software engineer who builds games — and understands how they break.
I'm a Senior Full-Stack Software Engineer, Roblox developer and Offensive Security Researcher based in Brazil.
I started building on Roblox in 2014. My work spans production backends, gameplay, networking, persistence and LiveOps, with server authority, performance and maintainability at the core.
Alongside engineering, I bring nine years in offensive security and AppSec: two assigned CVEs, three reported NASA vulnerabilities, and acknowledgements from GitHub, Google, Spotify, xAI and Tesla.
