01. Loopus López

Loopus López is a frantic arena survivor built in Unreal Engine 5 during the four-day GMTK Game Jam 2025. Our crew of four programmers, four artists, one designer, and one musician sprinted to deliver a looping combat experience full of exaggerated personality and reactive audio.

I engineered the enemy wave director: a C++ system that schedules spawns, escalates difficulty, and lets designers tune pacing without touching code. I also built the upgrade layer, covering UI flow, and the stat-modifier architecture.

Working under jam pressure pushed me to prototype fast while keeping pipelines tidy. Daily syncs with art and design kept scope realistic, and the debugging tools I scripted for balancing waves and power-ups were key to shipping a stable, punchy vertical slice within the deadline.

02. About Me

I'm Carlos Mazcuñán Blanes, a game programmer with an HND in Videogame Programming (ESAT). What really drives me is that moment when a technical problem that seemed impossible starts to make sense, when you find that elegant solution that makes everything click.

Core Skills

  • C / C++
  • Gameplay Systems
  • Unreal Engine 5
  • OpenGL / GLSL
  • Rendering Pipelines
  • Unity
  • Git & Perforce
  • Profiling & Optimization

How I Work

I specialize in gameplay and graphics, building robust and efficient systems in C++, Unreal Engine, and OpenGL. From rendering pipelines to internal tools, I like taking features from technical design to final polish.

But code is only one part. My teammates often say I'm the one who keeps the good vibe in the team. I believe communicating well and adapting to different ways of working is just as important as writing clean code. I'm comfortable working under pressure, and I enjoy that environment where everyone rows in the same direction to move a project forward.

I also code outside of work. I'm always tinkering with a side project or learning some new technology out of pure curiosity. After work hours, I keep coding because I enjoy it, whether that's personal projects or learning new things.

Let's Work Together

I'm currently open to new opportunities as a programmer. Whether you need gameplay systems, graphics features, or technical consultation, I'd love to hear from you.
