About this Gig
Need firmware that's reliable, efficient, and built to survive the real world?
I develop embedded firmware for ESP32 and STM32 microcontrollers from simple peripheral drivers to complete FreeRTOS-based applications with wireless connectivity, cloud integration, and Edge AI.
I don't just write code that works on a bench. I write firmware that handles real-world conditions: timing conflicts, sensor noise, power constraints, and communication failures.
What I specialize in:
- FreeRTOS task design and scheduling
- Sensor drivers and peripheral interfaces (SPI, I2C, UART, ADC, PWM)
- Wireless protocols LoRa, MQTT, BLE, Wi-Fi, GSM
- Low-power design sleep modes and duty cycling for battery and solar systems
- Edge AI deployment Edge Impulse and TensorFlow Lite on-device
- OTA firmware updates
- Cloud connectivity and dashboard integration
All code is version-controlled, documented, and delivered clean.
Message me before ordering to discuss your hardware and requirements I'll confirm feasibility and timeline upfront.

FAQ
Do you work with hardware other than ESP32 and STM32?
Yes — I also work with Arduino, Raspberry Pi, and nRF52 series. Message me with your platform.
Can you write firmware for hardware I've already designed?
Absolutely. Share your schematic and hardware specs and I'll take it from there.
Do you deliver source code or just binaries?
Always full source code with documentation — you own everything delivered.
Can you integrate my device with a specific cloud platform?
Yes — AWS IoT, Firebase, ThingsBoard, and custom MQTT brokers. Mention your platform when ordering.
What if my hardware has a bug causing firmware issues?
I'll flag it immediately with a clear explanation so you can fix the hardware side. I won't patch firmware to work around bad hardware design.
