Flint and Pixels 3D

Sun, 18 Jan 2026 00:00:00 +0000

Flint and Pixels 3D is a very small software-rendered 3D viewer written in C++ with SDL3, built as a learning project.

It loads .obj mesh files, parses vertex and face data, triangulates polygon faces, applies a minimal 3D transform pipeline, clips triangles against the near plane, projects the result to 2D, and renders the final wireframe in an SDL window.

I built it to experiment directly with computer graphics and the basic math behind it. Writing a tiny renderer from scratch was a practical way to study transformations, projection, clipping, and the relationship between 3D geometry and what eventually reaches the screen.

HojeNoRU API

This project is a bit outside my main interests in low-level systems and computer architecture. I built it as a practical web/API project: something useful, concrete, and relevant for rounding out that side of my portfolio.

HojeNoRU API is a REST API built to collect and expose the weekly menu of the UFRGS university restaurants.

It performs web scraping on the official menu source, stores the results locally, and exposes them through endpoints that let users query meals by restaurant, weekday, and meal type.

CNeander

Sun, 20 Jul 2025 00:00:00 +0000

CNeander is a command-line simulator for the hypothetical 8-bit NEANDER computer, created for educational use.

It loads memory files, validates their expected signature, executes Assembly programs for the architecture, and exports the final memory state in both binary and text formats.

I built it mainly to better understand the tools and concepts used in a computer architecture course. Reimplementing part of that environment in C made the instruction flow, memory format, and overall behavior of the simulated machine much more concrete to me than just using the existing tools as a student.
