Dimensia

Dimensia is the project that taught me how to build ambitious software — long before I joined Grammarly, GitHub, or Microsoft. I started it early in my engineering journey and still refine it from Berlin after spending time in Dresden.

A 2D platformer with a story-driven campaign, multiplayer experimentation, and a custom level editor. Every late-night Berlin iteration informs how I approach engineering during the day.

Story & World

Dimensia follows a lone explorer and his companion Henry as they test experimental suits across shifting dimensions. Each level forced me to try new mechanics, rendering tricks, and AI behaviors while balancing school and early internships.

Branching level arcs that reflect how I iterated on gameplay between Berlin and Dresden.
Multiplayer arenas built to stress-test networking ideas before I ever touched production services at Grammarly or Microsoft.
Environmental storytelling influenced by small commits, clear intent, and measurable outcomes.

Development Timeline

Started in my earliest coding days with C# and XNA, then moved to MonoGame during a Berlin refresh. Still a living lab for graphics, physics, and distributed playtests with friends across Germany.

Early Prototype: My first major graphical codebase, built during my first years of coding.
University Expansion: Refined tooling, added multiplayer sync, and experimented with shader packs.
Productization: Applied lessons from professional work — better CI, automated builds, and accessibility passes.
Berlin Era: MonoGame port with distributed collaborators, plus occasional Dresden playtest sessions.

Technology & Craft

I keep Dimensia aligned with my professional work by using the same engineering mindset I apply at Microsoft and learned at GitHub and Grammarly.

Core stack: C#, MonoGame, custom networking, and a level editor with reusable tooling.
Git-based branching, GitHub Actions builds, and async documentation so collaborators in Berlin, Dresden, and elsewhere stay in sync.
Privacy-safe telemetry to measure level completion and stability without exposing player data.

Download & Play

I release builds on request to keep track of feedback. Send me a note with your platform and I’ll share the MonoGame package along with setup tips.
