Sana Health
Wearable audiovisual therapy for recovery and mental wellbeing
The product
Medical wearable using audiovisual stimulation to support chronic pain, PTSD, and anxiety. James led as CTO across PCB design, electronics prototypes, firmware, Bluetooth, and mobile apps.
James was CTO at Sana Health, a medical device company building a wearable that uses audiovisual stimulation to support people with chronic pain, PTSD, and anxiety. He led the stack end to end: board schematics, electronics prototypes, firmware, Bluetooth, and the mobile apps that talk to the device. Today he mostly ships software, but that full-stack hardware background still shapes how he builds medical products.
What stood out
- Board schematics and PCB prototyping for the wearable
- Electronics prototypes built in-house, then refined toward a certifiable device
- Firmware and heavy Bluetooth Low Energy work to the phone
- Mobile apps that connect to the device and support the product experience
- End-to-end stack ownership from hardware through software
The stack he owned
- Schematics and PCBsCircuit board design and layouts for the wearable hardware.
- Electronics prototypesHands-on builds of boards and device electronics to get something real in the lab.
- FirmwareEmbedded software that runs on the device itself.
- BluetoothLow-energy wireless links between the wearable and the phone.
- Mobile appsiOS and Android experiences that pair with the device and the clinical workflow.
Building in healthtech?
Whether the hard part is the clinical workflow or the device that sits under it, James has shipped both.
