About this Gig
Your hardware idea deserves a real engineer not just a coder.
I am a certified Electrical Engineer specializing in ESP32 and STM32 firmware, IoT device development, embedded systems design, custom PCB layout, and sensor integration. I deliver complete, production-ready hardware solutions for startups and engineers worldwide from first concept to working prototype, all under one roof.
I develop optimized C and C++ firmware for ESP32, STM32, Arduino, and AVR microcontrollers with full support for UART, SPI, I2C, CAN, and Modbus protocols. For IoT projects, I deliver complete cloud connectivity via MQTT, HTTP, AWS IoT, Blynk, and ThingSpeak with WiFi and Bluetooth LE integration.
For PCB design, I create professional layouts in Altium Designer and KiCad with full DFM compliance and Gerber files ready for JLCPCB or PCBWay fabrication.

FAQ
Q: Do you build complete products from scratch?
A: Yes — schematic, PCB, firmware, sensor integration, IoT connectivity, and full documentation, all delivered together in one package without needing a second freelancer.
Q: Which microcontrollers do you support?
A: ESP32, ESP8266, STM32 F4/F7/H7, Arduino, PIC, AVR, and Raspberry Pi. Message me with your specs and I will confirm the best MCU for your exact requirements.
Q: Is the source code well documented?
A: Every delivery includes fully commented C/C++ firmware with a structured explanation document so your team can read, modify, and maintain it independently without confusion.
Q: Can you take over a broken or incomplete project?
A: Yes — I regularly rescue hardware projects that other freelancers could not complete. Share your existing files and I will give you an honest assessment before you commit to ordering.
Q: What cloud platforms do you integrate with?
A: AWS IoT Core, Google Cloud IoT, Azure IoT Hub, Blynk, ThingSpeak, and custom MQTT brokers — message me with your platform preference and I will confirm full compatibility.
Q: Do you provide post-delivery support?
A: Yes — Standard package includes 7 days bug support and Premium includes 14 days full support after delivery, so you are never left alone after the project is done.
