Hey there!
I'm Matheus
I've been building things for as long as I can remember, and for 10+ years I've done it professionally, shipping award-winning interfaces and backends trusted by millions.
Lately I've been aiming to join the gaming industry and finally fulfill a childhood dream, bringing all that passion and experience together into my portfolio project, Aethernal.
My experience
Over the past 10+ years I've worked across finance, energy, automotive, and the public sector, for clients that trust me to deliver. Lately I've been building AI-powered products for Mercedes-Benz, STADA, and the City of Maintal; before that, early-warning systems for Total Energies and large-scale public platforms for VisitScotland, Edinburgh University, and Edinburgh Library. Whether it's a secure finance journey or an experience used by millions, I'm always drawn to projects where design, usability, and technical depth come together to solve real problems.

Game Dev Journey
Outside of client work, I build multiplayer games, engineered like production systems. My core is server-authoritative netcode and backend, but I also bring what a small team feels every day: custom editor tooling that streamlines the workflow, game UI/UX shaped by years as a frontend engineer and ex-graphic designer, and the architecture and project-management instincts to keep a codebase healthy as it scales. The repos are private, but I'm happy to give you a live demo.
Aethernal
A Tibia-inspired, server-authoritative 3D MMORPG, built on Albion Online's architecture principles.
- Server-authoritative networking with client-side prediction & reconciliation on a fixed 20 Hz simulation tick.
- Area-of-interest management and a multi-mode dedicated-server topology (Host / Server / Client / Dedicated).
- Load-test harness that measures p99 tick times under clustered player loads, where the backend is treated as the game.

Becoming a Game Dev
Documenting my move into the games industry and everything I'm learning building Aethernal, one devlog at a time.
Aethermon
A creature-collector fan-game built as true multiplayer on Unity + FishNet, server-authoritative, where the server owns all state (no client-trust).
- Overworld, party/box management and turn-based battles running on an authoritative server (no client-trust).
- Reuses the networking patterns and tooling proven in Aethernal.
