Nikola R.

I design reliable, production-ready hardware for embedded systems and connected devices. With over 10 years of experience in PCB design, I’ve completed more than 50 successful projects for 30+ satisfied clients, ranging from low-power IoT devices to complex, high-speed multilayer boards. My work is guided by clarity, attention to detail, and long-term maintainability, from schematic capture and layout to testing and DFM optimization. While I occasionally write simple firmware for validation purposes, my true expertise lies in crafting robust, efficient, and well-documented hardware platforms. 🔧 Core Expertise: 🛠️ PCB Design – Up to 12 layers, impedance-controlled, HDI and rigid-flex 📶 High-Speed Interfaces – PCIe (Gen1–Gen4), USB 2.0 / 3.x, HDMI, MIPI CSI/DSI, DDR2/3/4, LPDDR4, SATA, eMMC, SDIO, RGMII, SGMII, QSPI, LVDS 📐 Signal Integrity – Length matching, differential pair tuning, impedance control, eye diagram and crosstalk simulation 🔌 Power Systems – DC-DC converters, LDOs, PMICs, battery management, multi-rail sequencing 📊 Test & Bring-Up – Lab validation, accessible layout for probing, test firmware and diagnostics ⚙️ Design for Manufacturing – BOM and layout optimization for reliable and cost-effective production I’ve contributed to projects in consumer electronics, industrial automation, medical devices, agriculture, automotive systems, space-grade electronics, and even radiation-tolerant systems developed for CERN's HL-LHC. If you’re looking for a hardware designer who understands both the science behind a clean layout and the real-world demands of scalable production, I’d be happy to support your next project.
