IoT Mobile App Developer
I build mobile apps that talk to real hardware — MQTT, AWS IoT Core, Bluetooth LE and geofenced device control.
Connecting an app to physical devices is its own discipline: unreliable networks, pairing flows, live telemetry and protocol correctness. I've shipped a production EV-charging platform on MQTT over AWS IoT Core with OCPP and Bluetooth LE — so I bring patterns that already work with real hardware in the field.
Device connectivity
MQTT over AWS IoT Core, real-time bidirectional telemetry, and resilient reconnection handling.
Bluetooth LE
BLE scanning, pairing and onboarding flows for connecting to hardware directly from the phone.
Protocols & standards
OCPP 1.6/2.0 for EV charging and structured messaging for custom device fleets.
Location & rules
Geofencing and location-bound sessions for hardware tied to a physical place.
How it works
- 01
Map the device-to-app message flow and failure modes first.
- 02
Prototype the connectivity layer against real hardware early.
- 03
Layer the product UX on a proven communication core.
- 04
Harden for flaky networks and ship to production.
Proof, not promises
