About this Gig
I design and develop complete embedded products from concept to working prototype covering schematic design, PCB layout, firmware development, and hardware testing.
Whether you are a startup, inventor, or product company, I handle the full development cycle so you get a production-ready device, not just code.
What I cover
- Schematic design and PCB layout (single and multi-layer)
- Component selection and BOM optimization
- ESP32, STM32, nRF52, and ARM Cortex-M firmware
- WiFi, BLE, LoRa, NB-IoT, and cellular integration
- RTOS-based firmware (FreeRTOS, Zephyr)
- Sensor, actuator, and module integration
- HMI display development using LVGL
- Hardware debugging and validation
- OTA updates and IoT cloud connectivity
What you get
- Complete schematic and PCB design files
- Clean, well-documented firmware source code
- Tested and validated hardware prototype
- Manufacturing-ready files (Gerber, BOM, assembly)
- Full documentation and easy handover
I have developed embedded products for consumer electronics, industrial automation, wearables, medical devices, and IoT systems.
Note: Message me before ordering, describe your idea and I will confirm what I can deliver.

FAQ
Which microcontrollers do you work with?
ESP32, STM32, and nRF52 are my primary platforms. Message me if you have a different chip.
Do you write bare-metal or RTOS-based firmware?
Both. I work with bare-metal C and FreeRTOS depending on what your project needs.
Can you add WiFi, BLE, or MQTT to my existing device?
Yes. Share your current code and hardware details and I will integrate the required communication stack.
Will I receive the source code?
Yes. You receive full, commented source code with documentation.
Can you optimize firmware for low power consumption?
Yes. I have experience optimizing sleep modes and power profiles for battery-powered devices.
Do you offer revisions?
Yes. Check each package for the exact number of revisions included.
Can you help if my firmware has bugs or is not working?
Yes. Share your code and describe the issue — I offer debugging as part of my service.
