About

Hey, I’m Marcius 👋 Link to heading

I’m a senior software engineer with over a decade of experience building scalable backends, distributed systems, and performance-optimized infrastructure. I’ve worked across industries — from security automation to cloud platforms — but lately, I’m diving deep into real-time multiplayer game networking.

🎯 What I’m Building Link to heading

This blog documents my journey building a real-time multiplayer game server from scratch, focusing on:

  • Tick-based simulation and game loops
  • Networked state synchronization
  • Client-side prediction and lag compensation
  • Matchmaking and lobby architecture
  • Scalable deployment with Docker & GCP

All written in Go (server) and C (client), with full source code, diagrams, and performance insights.

🧠 Why Game Networking? Link to heading

Multiplayer games are some of the most technically demanding applications in the world — combining low-latency networking, high-performance simulation, distributed services, and player experience. It’s the perfect playground to apply everything I love about systems design and software engineering.
