I help businesses design, build, and scale Internet of Things solutions by combining deep hardware knowledge with production-ready software engineering. With 28 years in the telecommunications industry, I’ve spent my career solving difficult integration, automation, and connectivity problems — the kind that don’t come with ready-made answers. My work has been recognized for innovation, and today I apply that experience to modern IoT, edge, and cloud-connected systems. Whether you’re building a prototype, stabilizing firmware, or scaling a deployed product, my focus is always on solutions that work outside the lab. 🔌 Connectivity & IoT Protocols 📡 LoRa and LoRaWAN solutions (LoRa and TTN certified) 📶 Cellular IoT: LTE-M, NB-IoT, LTE, 4G, 3G, 2G, GSM, GPRS 🔁 Protocols: MQTT, CoAP, REST, XMPP, Kafka, Google Cloud Messaging 🧠 Embedded & Firmware Development 🔧 Microcontrollers: ESP32, Arduino, STM32, RP2040 (Raspberry Pi Pico), Nordic RF, ATMEL, Microchip ⚙️ RTOS and OS: FreeRTOS, Zephyr, Embedded Linux 🧩 Firmware development in C/C++ using Arduino IDE or PlatformIO 🪛 Low-level device drivers and Linux kernel development 🤖 Automation & Edge Computing 🔗 n8n, Node-RED, Home Assistant, openHAB, IFTTT, Google Home 📦 Edge computing with Docker and balenaOS 🛠️ Infrastructure automation using Ansible, Terraform, or custom tooling ☁️ Cloud, APIs & Backend Systems 🧩 Full-stack development with Python, PHP (Laravel), and Nuxt 🔐 API design and development across 13+ programming languages 🌐 API gateways: Apigee (certified), Mulesoft, Kong ⚡ Serverless and microservices using AWS Lambda and Google Cloud Functions 📊 Data, Monitoring & Visualization 📈 Grafana, Prometheus, Datadog 🗂️ IoT platforms including ThingsBoard and DataCake 🧩 Hardware Design 📐 Schematic and PCB design using KiCad, Eagle, Altium, and OrCAD 🔍 Hardware bring-up, debugging, and power optimization 🧠 How I Work I take a system-level approach to every project, considering power, connectivity, firmware, cloud infrastructure, and long-term reliability from day one. My experience comes from real deployments, late-night debugging sessions, and production systems that had to work — not just demos. I’m instinctively drawn to interesting and unconventional challenges, especially where out-of-the-box thinking makes the difference. 🚀 Let’s Work Together If you have a tough IoT problem or a project that needs an experienced hand, I’m happy to review your requirements, suggest an approach, or help rescue a project that’s gone off the rails. menos
