Inertia Unlimited
Project Details
U-Boot Customization, Auto-Recovery System, and Qt-Based Camera Control Application for Inertia Unlimited, LTD
Client Industry
Inertia Unlimited
Inertia Unlimited is a Vermont-based leader in HD/4K high-speed specialty camera systems for sports broadcasting. They approached us with embedded system challenges: their custom cameras needed a robust bootloader, fail-safe recovery, and a user-friendly control interface. We performed U-Boot customization and implemented an auto-recovery system for their camera hardware, and developed a Qt-based cross-platform GUI for camera control. These solutions enabled Inertia to maintain reliable operation in live broadcasts, giving engineers a modern control app and ensuring the cameras reboot or recover smoothly after power faults, just as they needed.

Clearstone
Project Details
Development of a Thermodynamic Mathematical Library for Clearstone Engineering
Client Industry
Clearstone
Clearstone is an international environmental engineering firm specializing in air emission assessments and industrial air pollution control. They needed advanced simulation tools for their emissions projects. Specifically, we built a thermodynamic mathematical library to model gases and pollutants (e.g. combustion, carbon capture) within their software. Our library implements accurate equations of state and property calculations tailored to Clearstone's workflows. The result was a high-performance engine integrated into Clearstone's tools, allowing engineers to simulate emissions and optimize pollution-control processes efficiently and accurately.

Autokroma
Project Details
Development of an Upscaling Plugin for Autokroma
Client Industry
Autokroma
Autokroma is a software company that creates plugins for Adobe video tools (Premiere Pro, After Effects). They needed an upscaling plugin to enhance video resolution (e.g. upscaling pixel art or HD video). We developed this plugin according to their specifications, implementing sophisticated upscaling algorithms that run efficiently in the editor. The delivered plugin integrates into Autokroma's existing suite and gives users easy access to high-quality upscaling filters, improving their editing workflow and visual results.

Starchase
Project Details
GSM/GPS Module Integration for StarChase LLC
Client Industry
Starchase
StarChase, a public-safety technology firm, provides GPS tracking tools for law enforcement. Their systems let officers tag and track vehicles from a distance. We integrated a new GSM/GPS communication module into their device hardware. Our team wrote firmware and embedded code to enable reliable real-time tracking data over cellular networks. The result was a robust on-board system that tags suspects and transmits position data continuously to StarChase's mapping platform, enhancing pursuit safety.

Krita
Project Details
Expanding Compiler Support for Krita From MinGW to MSVC
Client Industry
Krita
Krita is a popular free/open-source digital painting program. The project was to expand compiler support from MinGW (GCC) to Microsoft's MSVC toolchain. We updated Krita's build system and source code to be compatible with MSVC, resolving Windows-specific issues and dependencies. This work enabled Krita to be natively built with Visual Studio, improving performance and allowing the Krita team to release an official MSVC-based Windows version. Our contributions broadened Krita's developer base and made builds more stable across environments.

Color Grading LLC
Project Details
Full System Architecture Redesign and Cross-Platform Migration for Cinema Grade
Client Industry
Color Grading LLC
Color Grading LLC develops "Cinema Grade," a point-and-click color grading plugin for editors (Premiere Pro, Resolve, etc.). They needed their entire software re-engineered and ported across platforms. We performed a full system architecture redesign and cross-platform migration. This involved refactoring legacy code and replacing dependencies so Cinema Grade could build and run on Windows, macOS, and Linux uniformly. Our overhaul ensured Cinema Grade's editor plugins now share a common codebase, making future updates easier and broadening compatibility, while preserving their intuitive grading workflow.
