About

Lucas Abreu

Computer Science graduate from UNIFEI, building games on the server side.

I believe gaming is a force for good in the world, and I'm always looking for ways to be part of that positive impact, whether that's working on a large-scale MMORPG or maintaining a MUD that's been a home for visually impaired players for over 20 years.

I got here through web systems development (dashboards, REST APIs, PHP and SQL) and that foundation turned out to be the perfect fit for the server-side work I do now.

Today I work at Insane Game Studios as a Senior Game Engineer on Profane, a Sandbox MMORPG. My focus is the backend and server-side: authoritative game logic, multiplayer systems, and the infrastructure that keeps a persistent online world running. I also actively use AI tools as part of my development workflow.

Project: Survivor

In Progress

A Vampire Survivors-style game built in Godot with C#, with a multiplayer design focus: spells from different players can interact, combining, bouncing, and chaining to create emergent combat combos. Built to learn Godot's node architecture and explore cooperative spell design.

Project: Souls

In Progress

A UI-only mobile game inspired by Spirit Stones. Players match groups of same-colored souls (alongside powerups) to generate attacks in a round-based system where enemies strike back every few rounds. No game world: all interaction is pure UI, making layout and tactile feel the central design challenge.

Games Played

Games aren't just work. They're what got me here. These are the worlds that shaped how I think about design, systems, and player experience. Working on them professionally is a dream come true. These are a few of my favorites.

Having a website is a great excuse for hosting pictures of cats!
