Krekeltronics designs and ships products end to end: application software, embedded firmware, electronics, and the path through certification and manufacturing. One senior engineering principal, augmented by an agentic development pipeline that compresses implementation time; clients work directly with the engineer who builds their product.

Selected work

GPS zone-guidance system — GPS positioning, BLE devices, mobile applications, cloud services, and an administrative dashboard, shipped as one product. The underlying inventions are patented (US 11,019,807; US 10,820,575; US 10,455,810).
Low-power clip-on instrument tuner — hardware engineered to simultaneous accuracy, latency, cost, and battery-life targets, through PCB design and environmental testing.
Thermal-imaging integration — EO/IR camera interface work and edge-TPU carrier hardware for machine-vision applications.
Embedded Linux firmware — Yocto-based images and SDKs for evaluation hardware; CoAP and BLE device protocols.
Commercial macOS audio engine — real-time engine, DSP, and application catalog rebuilt and shipping (Audiofile Engineering: Fidelia and the DDP tools).
Audio plugin development for a major hardware DSP platform.
