Project goals and challenges
Clairways Technologies needed an expert firmware code review for their ultra-low-power wearable respiratory monitor. The goal was to identify risks and improvements in stability, power consumption, and device readiness ahead of production constraints typical in medical/health devices.
Client Industry
Problem statement and solutions
Powerful, self-serve product and growth analytics to help you convert, engage, and retain more users. Trusted by over 4,000 startups.
Problem statement
Initial Situation
The device continuously captures respiratory signals on constrained hardware, making firmware correctness and power efficiency essential. Clairways wanted an independent review to de-risk critical paths and improve robustness before scaling.
Client’s Pain Points
They needed confidence in watchdog behavior, sleep/wake scheduling, sensor sampling correctness, fault handling, and overall code quality—while keeping battery life and stability at a high level.
Our solutions
We performed a structured firmware review: analyzing architecture, power management, error handling, and timing-critical sections. We provided prioritized findings and actionable recommendations, including refactor suggestions and test/validation steps suitable for embedded medical-adjacent devices.
Implementation Process
We reviewed the codebase with a focus on production risk: power, timing, reliability, and maintainability—then delivered a clear roadmap of fixes and improvements.
Our studio
Outcome and Impact
Stability
The review improved confidence in fault handling and long-run behavior for continuous monitoring.
Battery & Efficiency
Identified key optimizations to reduce power draw while preserving sampling fidelity.
Production Readiness
Provided a clear, actionable roadmap to harden firmware ahead of manufacturing and scale.

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.

Advanced Automotive Dashboard for Volcon Stag
Client Industry
Volcon
Volcon is an Austin-based maker of electric off-road vehicles (UTVs, motorcycles, e-bikes). They needed a modern automotive dashboard for the new Volcon Stag UTV. We designed and implemented an embedded dashboard system integrating vehicle telemetry (speed, battery level, drive mode, etc.) on a rugged display. Our solution used real-time OS techniques and a tailored user interface to ensure all critical information is displayed reliably. This dashboard fit Volcon's performance and durability requirements, providing Stag drivers with a responsive, easy-to-read control panel in the off-road environment.

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.
