Hire an IoT developer who owns everything from the device to the dashboard
Firmware, Bluetooth, cloud ingestion and live dashboards designed together, so the protocol, batching and power budget fit. My rehab platform streams 200Hz+ per device to clinicians at sub-100ms latency across 500+ concurrent sessions.

Why clients choose me as their iot developer
- ExperienceSenior, and proven in production6+ years, 17 shipped products and 6 P@SHA ICT Awards. Co-Founder & CTO, leading 25+ engineers, and still writing the critical code myself.
- ValueSenior expertise at a fraction of US/UK ratesI work remotely from Islamabad, so you pay well below US and UK senior market rates for the same depth, with working-hour overlap for the UAE, UK, EU and US East Coast.
- Low riskFixed-price prototype firstA free call, then a working prototype on your real data in about two weeks at a fixed price. You see results before any larger commitment.

Frequently asked questions
Do you handle firmware as well as the cloud?
Yes. ESP32 firmware, BLE GATT design and edge preprocessing, so both ends of the pipeline are designed together.
What throughput can you handle?
Reference numbers from my production systems: 200Hz+ per device, 500+ concurrent sessions, sub-100ms sensor to dashboard and under 50ms data to insight.
How much does it cost to hire you as a iot developer?
Every project is scoped on a free 30-minute call. Because I work remotely from Islamabad, you get senior, award-winning experience at rates well below US and UK senior market rates, and the prototype phase is quoted at a fixed price so your risk is capped.
Do you work with clients in the US, UK and UAE?
Yes. I have shipped for clients in UAE, UK, Australia and Pakistan, and work remotely with overlap for UAE, UK, EU and US East Coast hours.
Do you write the code yourself?
Yes. I architect the system and write the critical code myself. For larger builds I also lead engineers from my team at Quickgen Technologies, where I am Co-Founder & CTO.
