About this Gig
I provide professional embedded systems and IoT firmware development for Arduino, ESP32, and STM32 platforms. My services include embedded C/C++ programming, low-level peripheral configuration, sensor interfacing, real-time data acquisition, and reliable wireless communication using Wi-Fi, BLE, MQTT, and HTTP/HTTPS. I develop optimized, scalable, and modular firmware architectures with cloud integration for monitoring, control, automation, and data logging using platforms such as AWS IoT, Firebase, Blynk, and Thingspeak.
My solutions are suitable for IoT prototypes, MVPs, smart devices, industrial applications, and production-ready products, with focus on stability, performance, and future scalability. Code is clean, well-documented, and designed following embedded best practices.
️ Project discussion before placing an order is mandatory to finalize requirements, hardware selection, communication protocols, cloud architecture, timelines, and scope to ensure accurate and reliable implementation.

FAQ
Do I need to contact you before placing an order?
Yes. Project discussion is mandatory before ordering. This helps confirm hardware, sensors, communication protocols, cloud platform, scope, and delivery timeline to ensure a reliable and accurate solution.
Which microcontrollers do you support?
I work with Arduino, ESP32, and STM32 platforms. If your board is based on these MCUs, it is fully supported.
What type of IoT projects do you handle?
I develop IoT firmware for smart devices, automation systems, sensor monitoring, data logging, and cloud-connected products, including prototypes, MVPs, and production-ready systems
Which communication protocols do you use?
I support Wi-Fi, Bluetooth (BLE), MQTT, HTTP/HTTPS, UART, SPI, and I2C. GSM, LoRa, or other protocols can be added as extras.
Which cloud platforms can you integrate?
I work with AWS IoT, Firebase, Blynk, Thingspeak, and custom REST or MQTT cloud servers.
Will the code be production-ready?
Yes. I write clean, modular, and well-documented embedded C/C++ code, designed to be scalable and suitable for production deployment
Do you provide hardware or PCB design?
Yes. I provide hardware design and PCB design support along with embedded firmware development. This includes component selection, schematic guidance, pin mapping, firmware–hardware alignment, and PCB-level design coordination. Full PCB design, review, and optimization can be included based on proje
Can you sign an NDA?
Yes, I am happy to sign an NDA before starting confidential or commercial projects.
Do you offer post-delivery support?
Yes. Basic support is included, and extended support or modifications can be added as an extra.
Can you deliver urgently?
Yes, express delivery (24–48 hours) is available as an extra, depending on project complexity.
