About this Gig
Are your IoT prototypes failing at scale? Need commercial-grade firmware paired with a custom web portal?
I build production-ready IoT systems. By combining expert embedded C/C++ with Full-Stack Web App Development (MERN), I deliver secure, non-blocking edge-to-cloud architectures designed for the real world.
- Firmware: ESP32/STM32 via FreeRTOS. Multi-threaded, deterministicno amateur delay() loops.
- Hardware Protocols: RS485, Modbus, CAN bus, 4-20mA, DSP filtering.
- Telemetry: LoRaWAN, NB-IoT/Cellular, BLE, ESP-MESH.
- Cloud/OTA: Secure MQTT over TLS, AWS IoT Core, WebSockets, Remote OTA updates.
- Custom Dashboards: Dedicated React/Node.js portals with time-series databases. Say goodbye to basic templates.
- Edge Processing: State machines & ultra-low-power Deep Sleep profiles.
IDEAL FOR: Industrial IoT, AgTech, Hardware MVPs, & Smart Grids.
Why me? Scaling IoT fails when hardware devs don't understand the cloud, and web devs ignore microcontrollers. I expertly engineer both ends.
- Message me with your hardware, constraints, and project scope before ordering.

FAQ
Do you need my physical hardware to develop the firmware?
No.I develop and test using the same boards and sensors.I'll write firmware matched to your exact hardware, and I'll include a wiring diagram so you can set it up correctly.If I need to verify something specific about your setup, I'll ask for photos.
Can you work with my existing code?
Yes.I can debug, optimize, or extend your existing Arduino/ESP32 code.Just share your current sketch and describe what you need changed.I'll review it and quote accordingly.
Will I get the full source code?
Absolutely. You receive the complete, commented source code, wiring diagrams, and setup documentation. You own the code — it's yours to modify and use as you want.
What if the firmware doesn't work with my hardware?
I provide support after delivery.If something isn't working due to the firmware, I'll fix it at no extra cost within the revision limit.I also include troubleshooting steps in the documentation.
Can you integrate with Home Assistant or other smart home platforms?
Yes.I can set up MQTT output compatible with Home Assistant, Node-RED, or other platforms that accept MQTT data.This is included in the Premium package or available as an add-on.
Do you support sensors not listed inyour description?
Most likely yes.I've worked with a wide range of analog and digital sensors.Message me with your sensor model, and I'll confirm compatibility before you order.
Canthe web dashboard be accessed remotely (outside local network)?
The included dashboard works on your local WiFinetwork. For remote access, the Premium package includes MQTT cloud integration, which lets you view data from anywhere. Custom remote dashboard hosting can be arranged as an add-on.
Canyou add relay control to automate things (fans, pumps, lights)?
Yes.I can add relay control with threshold-based automation — for example, turning on a fan when temperature exceeds 30°C, or activating a pump when soil moisture drops below a set level.This is included in Premium
What boards do you support?
SP32 (all variants including ESP32-S2, S3, C3), Arduino Uno, Mega, Nano, ESP8266, and STM32 (Blue Pill, Nucleo).ESP32 is recommended for WiFi/Bluetooth projects.
