Description

I help small technical teams get connected hardware through the awkward middle: the prototype works, but field reliability, firmware recovery, device data or production testing still needs sorting.

I work across electronics, firmware, sensors, connectivity, telemetry and the practical QA around deployment. I built Aeroshi's connected indoor-air product from the device hardware through provisioning, authenticated telemetry, OTA updates, dashboards, manufacturing records and CE/RED technical evidence.

Best suited to focused technical rescue work, short fractional support and prototype-to-pilot projects. I work hands-on and leave behind a test, tool or process the permanent team can repeat.

INTERNET OF THINGS (IOT)
January 2025 - Today (1 year and 7 months)
• ▪ Built a connected indoor-environment monitoring product from concept to deployed units, covering custom sensor hardware, ESP32-C6 firmware, Wi-Fi provisioning, MQTT telemetry, cloud dashboards, QA workflow and deployment logistics.
• ▪ Integrated Sensirion SEN66 multi-parameter sensing for CO₂, particulate matter, VOC/NOx index, temperature and relative humidity, with device telemetry, device health reporting and room-level monitoring outputs.
• ▪ Developed repeatable provisioning, security and deployment scripts, reducing new device setup time to under 5 minutes.
• ▪ Implemented OTA update paths with rollback/partitioning and supported CE/EMC test preparation, including firmware adaptations for chamber conditions.

Embedded Systems Engineer
August 2024 - September 2025 (1 year and 1 month)
• ▪ Redesigned a low-power RF board to operate at <10 µA quiescent current, extending standby life and addressing customer complaints around battery drain.
• ▪ Pioneered an ITO glass solution that reduced system energy consumption by 75% and quiescent current by 50%, helping meet thermal and battery-life KPIs.
• ▪ Engineered a multi-board production test rig and resolved post-bootloader UART flag instability, eliminating line-stop failures during manufacturing ramp-up.
• ▪ Delivered an OTA audio pipeline across Python tooling and C firmware for bootloading, multi-chip communication and real-time DMA playback.
