About this gig
Why this gig?
I build production-ready mobile apps that connect real IoT devices to users and the cloud. Whether you need BLE pairing, secure Wi-Fi onboarding, MQTT telemetry, or NFC interactions, I deliver a stable app with clean UI, secure communications, and testable firmware hooks. I focus on results: shorter time-to-prototype, reliable device pairing, and a path to scale.
What I specialize in
- Cross-platform apps (Flutter / React Native) for Android & iOS.
- BLE (Bluetooth Low Energy): scanning, GATT services, background reconnection.
- Wi-Fi provisioning & secure onboarding (AP / SmartConfig / SoftAP flows).
- MQTT & real-time telemetry (QoS, retained messages, secure TLS).
- NFC interactions (read/write tags, HCE where supported).
- OTA hooks, device metadata sync, and backend-ready payloads (JSON, protobuf).

FAQ
I only have hardware specs. Can you still build the app?
Yes. I’ll work from your hardware datasheet (BLE UUIDs, NFC tag type, UART/serial spec). If a hardware sample is available I’ll get faster test results; otherwise I’ll mock the device behavior for integration and handover.
Which stacks do you use?
I primarily use Flutter for cross-platform speed and native plugin access (BLE, NFC). I can also deliver React Native or native Android/iOS modules on request.
Will the app work with my existing broker or cloud?
Yes. I support standard MQTT brokers (Mosquitto, EMQX, AWS IoT Core patterns).
How do you ensure secure device onboarding?
I implement secure Wi-Fi provisioning patterns, recommend per-device keys or tokenized onboarding, and use TLS for MQTT sessions.
What if my device uses custom BLE profiles?
That’s fine, provide the service/characteristic UUIDs and expected payloads. I’ll implement the correct GATT read/write/notify logic and test with a hardware emulator
What do you need from me to get started?
Hardware spec (BLE UUIDs or NFC type), example payloads, target platforms, and any UI preferences.
