Unity, gameplay systems, and WebGL delivery
Production work across Unity, Unity WebGL, Photon, C#, interaction systems, VFX, realtime environments, and delivery under actual device constraints.
About me
Freelance software developer based in Juiz de Fora, Brazil, building games, XR systems, browser-delivered 3D apps, multiplayer products, and hardware-linked interactive experiences across 15 years of production work.
I am based in Juiz de Fora, Brazil, and my path into software was practical before it was formal. I completed an IT technical program in 2005, spent two years studying physics at UFJF, and kept the useful parts with me: calculus, linear algebra, analytic geometry, and the habit of understanding systems from the inside out.
Outside client work, electronics sits much closer to hobby territory than career branding. I like building and testing things around 3D printing, small hardware experiments, reading, and games, and that curiosity still leaks back into the way I approach tools, interactivity, and problem solving.
In personal terms, I am a father, married, and living with three pets. That matters here because the work is not coming from a detached tech persona. It comes from a real daily life, which is probably why I care so much about building systems that are expressive, usable, and grounded instead of just flashy.

Apps + XR + Labs
Project range
Dream Machine XR, Conexao Estacao Natureza, Sutuverse, configurators, multiplayer apps, AI pipelines, kiosks, and hardware prototypes all sit inside the same professional profile.
How the work ships
I run my own delivery stack: dedicated servers on Hetzner, orchestration with Coolify, and tuned Redis, so projects stay responsive after launch.
The same discipline goes into content: Blender automation, Python scripting, and repeatable asset pipelines that keep 3D fast enough for real devices.
