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.

I’m an embedded Linux developer experienced in building tailored Linux images for embedded, or anywhere a customized Linux OS is needed, I bring 5+ years of seasoned expertise in the realm of Embedded Linux, coupled with a commendable 4+ years of hands-on experience in the field. My skills are : - • Embedded programming in C, C++, Python. • Yocto and Buildroot. • BSP (Qualcomm, NXP, Beagelbone, Raspberry Pi). • Linux kernel and user space drivers, device trees. • Emulation of firmware with Qemu.

Your prototype works on the bench. The first time a real customer plugs it in, it falls over — Wi-Fi setup fails, the firmware locks up after a week, the battery dies in three days instead of three months. That's the gap I close. I'm an embedded systems and IoT engineer. I take connected devices from "it works for me" to "it ships to customers and survives in the field." Most of my work falls into three areas: Embedded firmware on ESP32, STM32, nRF52, RP2040, AVR, and Raspberry Pi. C/C++ and Python. FreeRTOS and bare-metal. Low-power design when battery life matters — pushing sleep currents into single-digit µA, debugging the wake-up paths, tracking down the rogue peripheral that's keeping your device awake. Connectivity across BLE, Wi-Fi, MQTT, LoRa, LTE-M, NB-IoT, CAN, RS-485. Consumer IoT and headless devices. Captive-portal Wi-Fi onboarding so a non-technical customer can set up the device from their phone. Systemd watchdog services that recover from network drops automatically. OTA update infrastructure for fleet deployment. SD card write minimization on Linux-based devices, because the field failure mode no one warns you about is filesystem corruption six months in. PCB design when the project needs it. 2 to 8 layer boards in KiCad and Eagle, IPC-2221/7351 compliant. DFM and DFT review baked in from the schematic stage. Signal integrity, RF layout, and the kind of board-level decisions that affect yield, cost, and certification much more than firmware ever will. A few things worth knowing about how I work: I'm honest about scope. If your project doesn't need a custom PCB, cloud infrastructure, or edge ML, I'll tell you. I'd rather build the right thing for your actual budget than oversell. I think about the device's whole life, not just the demo. SD card longevity, Wi-Fi recovery, what happens when your customer's router changes, what happens when the firmware bug shows up in month six. The failure modes that matter are rarely the ones that show up on day one. I document for the human who comes after me. The setup guides and handoff docs I write are aimed at a non-technical reader — your future self, your in-house team, or whoever takes ownership when the contract closes. If you're building a connected device and the path from working prototype to shipping product isn't obvious yet, send me a message with what you're working on. I'll tell you honestly whether I can help.
