Hi, I'm Stephen, your IoT expert. I have a career spanning some 28 years in the telecommunications industry solving complex integration and automation problems which have enabled me to be a highly acclaimed and awarded innovative thinker. Today I take on a variety of challenges blending hardware and software to bring to life innovative solutions in the IoT (Internet of Things) space. Some of the challenges I can help with are: ✅ LoRa and LoRaWAN solutions (I am LoRa and TTN certified) ✅ Cellular solutions (LTE-M/NB-IoT, LTE, 4G, 3G, 2G, GPRS, GSM) ✅ IoT communications including MQTT, REST, XMPP, Google Cloud Messaging, and Kafka. ✅ Automation with Node-RED, Home Assistant, IFTTT, openHAB, and Google Home ✅ Hardware solutions with microcontrollers such as Arduino, ESP32, STM32, RP2040 (Raspberry Pi Pico), NordicRF, ATMEL, Microchip, and others ✅ Embedded development using Linux, FreeRTOS, Zephyr, and other tools on Raspberry Pi, x86, and other development platforms. ✅ Graphing through Grafana, Prometheus, Datadog, ThingsBoard, DataCake and others. ✅ Edge computing solutions using Docker or balenaOS ✅ Firmware development of Arduino using Arduino IDE or Platform IO in C++ ✅ Low-level device and driver development for the Linux kernel as well as microcontrollers ✅Full-stack software solutions using technologies such as PHP Laravel, NuXT, and Python ✅ Schematic and PCB development using KiCAD, Eagle, Altium, or Orcad ✅APIs in any of the 13 programming languages I know ✅API gateways such as Apigee (I am certified), Mulesoft, Kong, and others ✅ Microservices such as AWS Lambda, Google Cloud Functions, and others ✅ Automation with technologies such as Ansible, Terraform, or good old manual code I am a sum of my experiences and all those who came before me. Experience gained through sleepless nights, lost weekends, and holidays finding innovative and permanent solutions to challenges. Other experience has been gained through the skills, advice, and leadership of experts in this field over many years. I am instinctively drawn to interesting and unique projects so if you have a challenge that requires out-of-the-box thinking please do not hesitate to consider me.

LoRaWAN Private Network • $100 USD
Stephan was prefect for my needs as a programmer wanting to learn LORA & LORAWAN after almost a week of trying. In a couple hours, I learned what I had wrong, why, and how to avoid the mistakes. Then he was able to explain the other options for hardware and software that are currently available and the benefits.

Stephan is the real deal—a passionate expert electronics/embedded systems designer and programmer. He took our project as a personal challenge, going well above and beyond what we could reasonably expect. Stephan took ownership of our issues, used his own hardware and instruments to replicate our system, and gave it his full effort and attention until it worked flawlessly. He then meticulously tuned the system achieved the best possible performance. I give him my highest recommendations.

Lora and LoraWAN Project • $625 USD
I had a Lora Project which I didn't know was possible and asked if Stephan could make some progress to see if it was possible. Not only did he make my Lora project a reality he went above and beyond to make a beautiful solution with great documentation!
