Mobile apps that drive spectroscopy sensors over Bluetooth.

Tellspec's handheld NIR sensors can analyse food, fish and human milk, but only through software that calibrates them, runs scans over Bluetooth and turns raw spectra into results people can act on: in the field, in a lab or in a hospital.

React Native apps that pair with the sensors over BLE, handle calibration and scanning, and report results live from Tellspec's cloud machine learning. Plus two EU-funded products, MyNutri and FishTell, built from scratch across mobile and web, and clinical platforms for milk analysis.

I owned frontend and mobile delivery: the BLE integration and native Android SDK changes, the app architecture, the API integration with the cloud, and the web platforms clinical teams use.

Radio links that drop, device calibration, native SDK code and clinical data that has to be right. Hardware, not just screens.

Five products shipped across food spectroscopy, nutrition and clinical milk analysis, including two EU-grant apps delivered from zero.
