About this Gig
I build ESP32 IoT systems that work reliably in the real world. With a 4.9 rating and repeat international clients, I deliver everything from single device firmware to complete multi node LoRa networks with live dashboards and remote control. Recent builds span mining hardware, factory monitoring, power sector systems, and agriculture.
What I offer:
- Firmware development: clean, optimized ESP32 code in C/C++ (Arduino or ESP-IDF)
- Hardware: sensor integration, component selection, and circuit guidance
- Connectivity: MQTT, Wi-Fi, and LoRa point to point or multi node
- Cloud dashboards: real time monitoring with ThingSpeak, MQTT, or a custom web dashboard
- Documentation and support: step by step guides, full source code, and live remote support
How it works:
- Message me with your idea or the problem you are stuck on
- We agree on scope, milestones, and timeline
- I build, test, and demo the system working
- You receive the source code, documentation, and deployment support
Every delivery is tested end to end before it reaches you. Please message me before ordering so we can match your requirements to the right package.
FAQ
What kind of IoT projects can you develop?
I can develop projects including smart home automation, environmental monitoring, industrial sensor networks, multi-node LoRa systems, GPS tracking, GSM/GPRS-based IoT, and more.
Which platforms and boards do you work with?
I primarily work with ESP32, Arduino, Raspberry Pi, STM32, LoRa modules, and other microcontrollers as needed.
Do you provide sensor integration?
Yes! I can integrate temperature, humidity, accelerometer, ultrasonic, microphone, pressure, gyroscope, camera, GPS, and more. Custom sensors can also be added based on your requirements.
Will I get the source code and documentation?
Absolutely! Every project comes with well-commented source code, wiring diagrams, and detailed documentation for easy understanding and future modifications.
Can you help with cloud dashboards?
Yes, I can set up real-time dashboards using ThingSpeak, MQTT, or custom web dashboards for monitoring and controlling your IoT devices.
Do you provide remote support or guidance?
Yes! I offer Zoom or TeamViewer sessions to guide you through setup, debugging, and project deployment.
How long does a typical project take?
Delivery time depends on project complexity. Basic projects take 3–5 days, standard sensor-integrated projects 7–10 days, and full multi-node systems 14–21 days.
Can you scale projects to multiple nodes?
Definitely! I specialize in LoRa mesh and multi-node communication, enabling large networks with seamless data flow.
