I help startups, individuals and product teams turn electronic product ideas into reliable, production-ready hardware. Most projects don't start with a clean spec. There is usually a rough concept, an early prototype, or a design that is not behaving as expected, sometimes one that has already failed an emissions test. That's typically where I come in. I work across the full development process, from system architecture and component selection through schematic design, PCB layout, firmware, prototype assembly, bring-up, testing, and manufacturing handoff. The goal is not just to make something that works, but to build hardware that remains stable, repeatable, and manufacturable. A big part of my work is preventing problems early. Poor power design, RF issues, EMI, or layout decisions that cause instability later are common failure points. Fixing these after prototyping is costly, so I focus on getting the fundamentals right from the start, and I verify them in my own lab before a design goes to certification. My work includes: * Schematic design and multi-layer PCB design (Altium Designer) * Embedded systems and firmware (C, C++, Rust, Embedded Linux) * Hardware debugging and root-cause analysis * RF design (BLE, Wi-Fi, LTE, GNSS, Sub-GHz) and antenna integration * Power electronics (DC/DC, battery systems, charging, PoE, BLDC/FOC motor drives) * Precision analog, sensor front ends, TEC/Peltier and piezo/high-voltage drivers * In-house validation, testing, and pre-compliance checks * DFM/DFT and manufacturing handoff (BOM, Gerbers, assembly documentation) I maintain a fully equipped lab for bring-up, testing and EMC pre-compliance, with my own pick-and-place for prototype builds, which allows issues to be identified and resolved early, before they reach production. I've worked on IoT devices, wearables, and industrial systems using platforms such as STM32, ESP32, nRF52/nRF53, and i.MX. I work directly with clients, keep communication clear, and stay involved until the design is stable. No handoffs, no guesswork, and no disappearing after the first prototype. If you're building a hardware product and want it done properly from the start, or need to stabilize an existing design, feel free to get in touch.
