Glenn Genre Mamanao

I build things across the full stack — from Flutter UIs and FastAPI services to custom voxel engines in C++. Currently at MBOX Smart Lockers shipping production software that runs IoT systems and internal tooling.

About

Developer.
Philosopher. Chef.

I think of engineering the way Nietzsche thought of the self — as something to be continuously refined, never finished. Every system I build is just another iteration in that process of becoming.

By day I'm navigating the full stack: Flutter frontends, FastAPI backends, Go services, and occasional deep dives into C++ and OpenGL when I want to understand what's actually happening beneath the abstraction.

Off the clock, I'm in the kitchen dialing in the perfect adobo — same obsession with getting things right, different medium.

Voxel Engine

A custom 3D voxel-based game engine written from scratch in C++ and OpenGL. An exercise in understanding what's happening beneath the abstraction — raw memory, the GPU pipeline, and geometry built by hand.

  • Custom GLSL vertex and fragment shaders.
  • Vertex Buffer Objects (VBOs) and VAOs managed manually.
  • Raycasting for block selection and collision.
  • Procedural chunk generation.
C++ OpenGL GLSL
