Engineering a mission critical power management firmware at Boeing allowed me to reduce power consumption by 15 percent on a remote sensor array used in extreme flight environments. This challenge required optimizing low level interrupt handling and managing peripheral sleep states across resource constrained hardware. Developing reliable solutions for harsh field conditions defines my approach to embedded architecture. My tenure at Honeywell and Boeing shaped my ability to deliver robust code where every microsecond and milliwatt matters. Joining the product development team at Axon presents a unique opportunity to apply this rigorous testing methodology to safety hardware.
My work at Honeywell involved porting a legacy bare metal motor control loop to a modern Cortex M4 core, which resulted in a 25 percent improvement in motor responsiveness by leveraging optimized Assembly routines. While at Boeing, I overhauled a FreeRTOS task scheduler to eliminate priority inversion, cutting system jitter by 40 milliseconds. Additionally, I implemented automated hardware in the loop testing with Python, reducing regression testing time by 20 hours per sprint. Utilizing Rust for memory safe peripheral drivers further solidified my ability to write secure, performant software for complex embedded platforms.
Axon stands out because of the integration between wearable device hardware and real time network connectivity which demands extreme code reliability. My expertise in building deterministic systems using Zephyr and bare metal C aligns with the architectural requirements for your Taser and body camera product lines. I bring a deep understanding of hardware abstraction layers and signal processing that complements your current development efforts. My background managing high stakes embedded lifecycles ensures that I can contribute to the development of your next generation connected safety devices immediately upon joining the firm.
I welcome a discussion regarding how my experience in high reliability firmware design supports the specific goals of your product development team. My technical depth in C and Rust combined with extensive experience in the aerospace and defense sectors provides a solid foundation for addressing the complex integration challenges found within your ecosystem. Please let me know your availability for a conversation next week to review my approach to these engineering problems. I look forward to contributing to the impact that Axon products have on public safety globally.
Best regards,
Andre Johnson
