I will be your iot developer for esp32, lora, mqtt, node red, and raspberry pi
Full Stack IoT Embedded System Engineer , ESP32 Firmware , PCB Design
Building electronics since age 13, I am a Senior IoT Engineer who bridges the gap between hardware and software. I don’t just write code; I design custom PCBs, write robust Firmware (ESP32/C++), and b...
About this Gig
Is your IoT project stuck at the hardware-software gap?
Most builds fail at the same points dropped MQTT connections, unstable GSM links, or firmware that works on the bench but fails in the field.
I'm Ramim, an embedded systems engineer specializing in ESP32, Arduino, Raspberry Pi, LoRa, ESP-NOW, MQTT, Node-RED, Firebase, and GSM from sensor to cloud.
What I deliver:
- ESP32 & Arduino firmware clean, commented, production-ready
- LoRa & ESP-NOW for long-range, low-power industrial IoT networks
- MQTT, Firebase & HTTP cloud connectivity with real-time dashboards
- Raspberry Pi edge gateways with GSM/4G and Node-RED pipelines
- Component list, system design & full technical documentation
Why IoTWithRamim:
- Hardware-first engineering I understand silicon, not just code
- Secure, scalable cloud architecture built from day one
- Clean, maintainable firmware with clear documentation
- Proven across industrial, agricultural & humanitarian deployments

FAQ
Do you ship hardware or components to my country?
I deliver firmware and software only — no hardware is shipped. After ordering, I provide a full components list with supplier links (Amazon/AliExpress) so you can source locally at the best price.
Will I receive a components list so I know exactly what to buy?
Yes. Every order includes a detailed BOM (Bill of Materials) — part names, quantities, spec sheets, and sourcing links. Standard and Premium packages also include substitution options if parts are unavailable.
Can my system scale to more devices or sensors in the future?
Yes — scalability is built in from day one. LoRa/ESP-NOW networks support dozens of nodes. MQTT brokers handle hundreds of clients. Adding a new device means flashing existing firmware with a new node ID.
What technical support do you offer after delivery?
All packages include post-delivery support within the revision window. For long-term maintenance, I offer affordable support packages via Fiverr. Message me to set up an ongoing arrangement anytime.
I'm not technical — will I be able to use what you build?
Absolutely. Every delivery includes a plain-English setup guide, wiring diagram, and dashboard built for non-technical users. If you can use a smartphone app, you can operate the system I build for you.
