About this Gig
I develop production firmware across the full Nordic lineup. On nRF52840 and nRF52833 I implement custom BLE GATT profiles, DFU (device firmware update) over BLE, Zigbee and Thread stacks, and aggressive power optimization using system off mode and timed wakeup. On nRF9160 I build LTE-M and NB-IoT asset trackers, cloud-connected sensor nodes, and GNSS positioning systems using the modem firmware and nRF Cloud or custom backends.
My Zephyr work covers device tree configuration, custom board definitions, driver development, and multi-core coordination on the nRF5340. I do not write against the deprecated nRF5 SDK unless your project already depends on it.
Clients I’ve worked with
Oasis Water Technologies
Collaborated with multiple teams at Oasis to engineer a highly durable, battery-powered industrial IoT device. Because the device was designed for remote deployments with minimal human interaction, mission-critical reliability was the top priority. I delivered an end-to-end solution, handling the custom hardware design, robust firmware development (including WiFi, OTA updates, and MQTT protocols),

Mobile Outfitters
Partnered with Mobile Outfitters to engineer the core electronics for a high-precision, CNC-style mobile accessory cutting machine. Tasked with solving a complex integration of digital and analog circuits, I managed the full hardware lifecycle—from initial schematic design and high-density PCB layout to troubleshooting and prototype testing. The project resulted in a fully manufacturable, producti

FAQ
Do you work with nRF5 SDK or only nRF Connect SDK / Zephyr?
I work in both. For new projects I recommend nRF Connect SDK with Zephyr. If your product already runs on nRF5 SDK I can maintain and extend it without a migration.
Can you design the nRF hardware / PCB as well?
Yes. I design RF-aware PCBs with proper antenna placement, impedance matching, and regulatory layout guidance. Message me for a combined quote.
Do you handle BLE certification prep?
I can structure the firmware and provide the documentation typically required during BLE SIG qualification prep, but formal certification testing is done by an accredited lab.
Can you add Zigbee or Matter to an existing nRF52 project?
Yes, provided the target is an nRF52840 or nRF5340 with sufficient flash. Share your current project and I will assess compatibility.
