Analog and digital designer. Programmer of micro controllers in C or Assembly. Schematic, and PCB design and manufacture. 35 years experience in the electronics industry, from R&D to industrial systems. BSEE: Devry Institute of Technology 1979-1980 & 1987-1988. I have been involved with electronic engineering, and systems repair for the last 35 years. I have designed everything from radios to computers, and everything in between. My methods are simple. Design the needed system, do the coding, prototyping, and testing. if all tests pass.then create the schematic, design the PC board and Gerber files, and have some samples manufactured. Then in the lab solder all components on the board, whether through hole or surface mount types. Test the circuit board, and deliver the product with all details.

Senior IoT Engineer building complete IoT systems: the firmware on the device, the cloud that receives its data, and the tools to run a fleet of them in production. RECENT WORK For several years I've owned the platform behind a fleet of EV energy-management controllers - ARM Linux devices that measure a site's electrical load and allocate current between chargers in real time. Real-time sampling runs as bare-metal firmware on the SoC's real-time core and feeds a multi-threaded C++ application through shared memory. Around it: U-Boot boot flow, device-tree overlays, GPIO/I2C/SPI peripherals, Modbus and OCPP to third-party equipment. An A/B update system that cannot brick a device: two system slots plus a persistent data partition, signed bundles, a bootloader-side attempt counter that falls back before Linux starts, and a health check that confirms a new image or rolls it back by itself. Proven on hardware, including power cuts mid-update. A fleet-wide Debian migration done remotely: repartitioning live devices in place, carrying each unit's identity (certificates, VPN keys, calibration) across, and keeping a working fallback until the new system proved itself. No site visits. Cloud side: MQTT telemetry and commands to AWS IoT, Lambda processing into the fleet database, per-device certificate provisioning, WireGuard access to devices behind customer NAT. WHAT I DO Embedded: C/C++ firmware; embedded Linux (Debian and Yocto - own layers, recipes, images); U-Boot, device tree, kernel configuration, board bring-up; drivers and hardware integration; Modbus, TCP/IP, UART, SPI, I2C; performance work and hard-to-reproduce bugs. Updates: A/B images with automatic rollback; signed bundles and key rotation; staged fleet rollouts; application updates from a private, certificate-protected package repository. AWS: IoT Core and MQTT architecture; Lambda services; cloud databases; device provisioning and certificate management; telemetry and remote monitoring; designs that stay cheap as the fleet grows. Python: backend services and APIs; automation and build tooling; data processing; device-management services. Platforms and remote access: fleet-management web apps and real-time dashboards; remote firmware updates; WireGuard VPN and secure SSH tunnelling; diagnostics for devices with no public address. WHY ME Most IoT problems live between the layers - a device reporting the wrong state, an update that works on the bench and fails in the field, a cloud message nobody can trace back to the firmware that sent it. Instead of coordinating separate firmware, cloud and web developers, you get one engineer who follows a problem from the bootloader to the dashboard and designs the pieces to fit. Let's talk about what you are building and find the shortest path to something production-ready.
