The Sandbox

The Sandbox Explainer: What is The Sandbox? Official Website

"The Sandbox" is a decentralized virtual gaming platform and metaverse where users can create, own, and monetize experiences using blockchain technology and NFTs. It provides tools like VoxEdit and the Game Maker to empower creators, while its marketplace allows trading of virtual assets and land parcels.

I played a key role in implementing critical features and enhancing the user experience, the primary achievement was designing and deploying a modular character controller, replacing the legacy system with a production-ready solution. I also developed an automated playtesting framework, implemented a Feature Flag system, and evaluated chat SDKs, presenting options to C-level stakeholders and integrating the chosen solution.

The Sandbox is available as public alpha.

Tools used: Unity3D (ECS), JetBrains Rider, Git, Notion

The Great Sassanelli

As sole programmer I was in charge of developing a prototype that could be used to aquire publisher and investors. The core part was the implementation of the Inkle Engine into Unity3D.

The game is still in active development and planned to be released in Q1 2025.

"Ein Fuchs im Netz" is a point-and-click adventure for mobile games, teaching children about cybersecurity and preparing them for the dangers on the internet. The player helps cyber-fox Finn, who has crash-landed on Earth, to repair his spaceship so that he can continue his travels in space.

The game can also be expanded using a Micro:Bit or Calliope mini-computer.

Joining the project in a later stage of development, I was in charge of porting the app to iOS and Android devices. Later I took over the role as lead developer and coordinated the work of three developers, including code review and mentoring.
