Sensor & analog front-end design
Sensor selection, analog conditioning, ADC integration, and noise budgeting. Calibration pipelines for temperature, humidity, gas, optical, ECG, soil moisture, and beyond.
End-to-end IoT product engineering for the things that touch human life directly — wearables and medical devices, agricultural sensing, and home-health monitoring. Sensor design, edge firmware, secure connectivity, cloud telemetry, and the field-grade hardening real deployments demand.
An IoT system is the most full-stack discipline in modern engineering. A single product touches sensors, analog conditioning, embedded firmware, low-power radio, certificates, gateway software, cloud telemetry, dashboards, and the operational discipline to keep all of it alive in the field.
We focus our IoT work on domains where the work touches human wellbeing — health and medical devices, agricultural sensing that protects food security, environmental and home-health monitoring, and wearables. Where IoT is doing real work for real people.
We design and build to standards consistent with what large platform companies like Google, Microsoft, AWS, and the major silicon vendors expect from connected fleets at scale: secure boot, OTA, certificate lifecycle, observability, and a path to certification.
Sensor selection, analog conditioning, ADC integration, and noise budgeting. Calibration pipelines for temperature, humidity, gas, optical, ECG, soil moisture, and beyond.
Bare-metal, RTOS, and Linux-class firmware on ARM Cortex-M, Cortex-A, RISC-V, and ESP32. Power-budget aware, deterministic, OTA-ready.
BLE, Wi-Fi, LoRaWAN, NB-IoT, LTE-M, Thread, Matter, Zigbee, and proprietary sub-GHz. Co-existence, link budget, and field-RF tuning.
On-device inference for anomaly detection, classification, and event triggering. TinyML, quantized models, and hardware-aware optimization for sub-mW MCUs.
Secure boot, key provisioning, identity-per-device, mutual TLS, hardware root-of-trust (PSA Certified, TPM, SE). Threat modeling and pen-test readiness.
Ingest pipelines, time-series storage, fleet management, OTA orchestration, dashboards. AWS IoT Core, Azure IoT Hub, GCP IoT, or self-hosted.
Medical (IEC 62304, ISO 13485), agriculture (ISOBUS), industrial (IEC 61131-3, OPC UA), and FCC / CE / IC RF certification readiness.
Design for testability, factory provisioning, calibration jigs, field diagnostics. The unglamorous discipline that decides whether 10,000 units actually work.
A practical, opinionated stack — chosen for production reliability, not novelty. We add to it carefully, and we share what we learn.

We work with a small number of partners each year. The right first step is usually a conversation. Or look at how we validate.
