The desktop administration tool for SkyMatrixControl. It gives authorised engineers a central way to manage tablet deployments over Tailscale, including configuration, diagnostics, licensing and remote APK updates.

• Authenticated remote configuration and diagnostics
• RSA licensing and SHA-256 APK validation
• Remote restart, reboot and deployment workflows

A C++ video wall for viewing multiple CCTV feeds on a Raspberry Pi, with layouts that adapt to the camera grid.

• Multi-camera viewing
• Dynamic grid layouts
• Web configuration

A self-hosted dashboard giving authorised engineers direct access to remote-site devices, without relying on a Windows PC and paid remote-access seats. Site information, device status and web-interface links are brought together in one place.

• Unique virtual subnets for overlapping networks
• Pi monitoring, SSH maintenance and network scanning
• Automated site provisioning with Bash

A collection of tools for the less visible work around a site: configuring cameras from different manufacturers, redacting footage and keeping digital signage running on schedule.

• Mixed-manufacturer camera setup
• GDPR footage redaction
• Scheduled signage with remote control

A 3D football coaching application for Windows and macOS, used by football organisations across Europe.

• Custom physics and timeline systems
• Kit creator and stadium rendering
• Python session builder with local AI authoring

A session-building tool that talks to a local language model to create football coaching sessions. It writes session files in the format the main CoachFX Unity application can load and use.

• Describe a session in natural language
• Generate CoachFX-compatible session files
• Load the resulting sessions in the Unity application

An environment-authoring toolkit that makes world building in Unity feel like one editor instead of a chain of separate utilities. Terrain generation, brush sculpting, layered materials, constrained scattering and metaball forms share the same data contract, so a landscape goes from empty scene to finished environment without leaving the Scene view.

• Custom Inspector and Scene-view tooling with brushes, stamps and undo-safe painting
• 230-layer texture-array materials with camera-adaptive tessellation and displacement
• Terrain-aware object blending, constrained scattering and procedural metaball geometry

A Java frontend for managing and launching console emulators, with a media-rich library, per-console themes and tools for keeping a game collection organised.

• Console library with cover art, logos and screenshots
• Video trailers, manuals, Steam achievements and HowLongToBeat times
• Playlists, image tools, screenshots and an achievement creator

A water bottle created from scratch as topology practice, finished with custom-made procedural materials.

• Modelled from scratch
• Topology and subdivision study
• Custom procedural material work

A bathroom redesign visualisation created for a client in 2018, using 3D modelling, materials, lighting and multiple views to communicate the proposed layout.

• Client project · 2018
• Material and lighting studies
• Multiple camera views
