For a connected or smart device, I write the software that runs it, firmware, device communication and the companion app, to your hardware team's specification. This is a software-only engagement: I don't design or manufacture the hardware, and I'm upfront about that boundary before we scope anything.
Written to your hardware spec · C/C++ & MicroPython · BLE / Wi-Fi / Modbus / CAN · Delivered ready to flash
A software-only engagement with a boundary you can see before we start, so there's no surprise halfway through the build.
The layers are the how. These are what your hardware team actually gets.
Firmware that runs the device. Core logic, state handling and power management in C/C++ or MicroPython, written to your controller and hardware spec.
Sensors and peripherals, handled. Software to read and act on your sensors and actuators, moving data reliably between the device and its controller.
The device talks cleanly. Communication over BLE, Wi-Fi, serial, Modbus or CAN, so it connects to a phone, gateway or cloud service without drama.
A companion app to control it. A mobile or web app to pair with and drive the device, built on the same stack as my platforms.
Telemetry you can watch. A Supabase or Azure pipeline for logs, telemetry and remote monitoring of your fleet.
Tested and handed over. Validated on your provided hardware, delivered ready to flash, with documentation your team can maintain.
We agree the boundary, controller, sensors and protocols.
Core logic, sensors and peripheral handling written and unit-tested.
BLE / Wi-Fi / CAN layer plus the app and cloud pipeline.
Validated on your hardware, delivered ready to flash with docs.
Take the whole software stack or the layers you're missing. All written to your hardware team's design.
Core logic, state handling and power management, C/C++ or MicroPython.
Read and act on sensors and actuators, reliable device data flow.
Wireless links to a phone, gateway or cloud service.
Industrial and wired protocols as your hardware requires.
Mobile or web app to pair with and control the device.
Supabase or Azure for logs, telemetry and remote monitoring.
Verified on your provided hardware before handover.
Code delivered ready to flash to your chip.
Documentation your hardware team can maintain going forward.
A single point of contact who writes the firmware, the app and the cloud, and is honest about the hardware line.
I write device software end to end, firmware, communication and the companion app and cloud, to your hardware team's spec. My background spans embedded C/C++, .NET/C#, Python and cloud on Azure and Supabase, and four years in healthcare technology at TCS. I keep the scope software-only and say so up front, so you always know exactly where my work ends and your hardware team's begins.
No. This is a software-only engagement. I write the firmware, device communication and companion app to your hardware team's specification. I don't design PCBs, manufacture hardware, or do mechanical or enclosure design, and I make that boundary clear before we scope anything.
Embedded firmware in C/C++ or MicroPython depending on your controller, covering the device's core logic, state handling and power management.
Communication layers over BLE, Wi-Fi, serial / UART, Modbus or CAN as your hardware requires, so the device talks cleanly to a phone, gateway or cloud service.
Yes. Code is delivered ready to flash to your chip, with documentation your hardware team can maintain going forward.
Yes. Testing and validation are done on your provided hardware before handover.
