Most hardware projects don't fail because of bad ideas. They fail in the messy space between "working prototype" and "shipping product." That's where I've spent the last 14 years — across 350+ projects and 50+ products now in mass production. Hundred clients have come back for a second project. Here's what's behind that number. I take products from napkin sketch to factory floor — designing the PCBs, writing the firmware, and optimizing the BOMs. That DFM work alone typically saves clients 20–30% on production costs. One client shipped at 12mA after coming to me with a prototype drawing 800mA in sleep mode. That's the difference between a redesign and a launch. The firmware I write runs 24/7 in industrial environments where a crash at 2 AM means someone's driving to a job site. I build for reliability first: FreeRTOS or bare-metal on STM32, ESP32, nRF52/53, RP2040, PIC, and Atmel. Connectivity — MQTT, BLE, Wi-Fi, LoRa, or cellular — gets chosen for the use case, not the trend. On the hardware side: multi-layer PCBs, proper signal integrity, IPC-compliant layouts (2221, 7351) in Altium and KiCad, built for manufacturability from day one. When the project calls for it, I wire the full IoT stack — AWS IoT Core, edge AI/ML inference, secure OTA, and fleet health monitoring. Top-Rated Plus. 100% Job Success Score. If you need an engineer who thinks in yield rates, field reliability, and unit economics — hit "Message" or "Invite to Job." Let's get your product out the door.
