About

From Prototype to Production — IoT Done Right

I’m a seasoned IoT and Embedded Systems Engineer with 28 years of real-world experience building reliable, full-stack connected solutions. I help businesses and innovators design, develop, and deploy robust IoT products and systems — from edge firmware and hardware to cloud APIs and data pipelines.

What sets me apart is the breadth of my skills and depth of my experience: I’ve solved complex integration challenges across telecommunications, embedded platforms, automation, and large-scale backend environments. My work spans:

🔧 Embedded & Firmware Development — ESP32, STM32, RP2040, Arduino, FreeRTOS, Zephyr
📡 Connectivity & Protocols — LoRa/LoRaWAN (certified), MQTT, CoAP, REST, LTE-M, NB-IoT
☁️ Cloud & Backend — APIs, serverless (AWS Lambda, Google Cloud Functions), robust integrations
📊 Data & Monitoring — Grafana, Prometheus, Datadog, ThingsBoard
🤖 Automation & DevOps — Node-RED, Home Assistant, Docker, balenaOS, Terraform, Ansible
📐 Hardware & PCB Design — KiCad, Eagle, Altium, Orcad, prototyping to production

I also bring hands-on lab capability — oscilloscopes, logic analyzers, RF and spectrum analysis — enabling confident system validation and pre-compliance testing.

I take a systems-level approach, ensuring every component — hardware, firmware, connectivity, cloud, and data — works reliably together under real-world conditions. I enjoy tackling challenges that require thoughtful architecture, elegant engineering, and scalable results.

If you’re building a connected product, need to solve persistent IoT issues, or want an experienced partner who can deliver from prototype to production with long-term support, let’s connect.

Work Terms

I operate with a client-first approach, aligning my availability with your organization’s schedule and timezone to ensure effective coordination and timely delivery.

Engagements are structured around clearly defined scopes of work and mutually agreed milestones. Payments are aligned with the successful completion of these milestones, ensuring transparency, accountability, and measurable progress throughout the project lifecycle.

I adapt to your organization’s preferred communication protocols — whether that involves formal reporting structures, documented status updates, scheduled review meetings, or integration into existing project management systems. My objective is to integrate seamlessly into your operational framework while maintaining clear governance and delivery discipline.

I am committed to professional standards, structured execution, and long-term collaborative relationships built on reliability and results.
