I help startups and enterprises transform ideas into reliable, scalable, and production-ready electronic products. My expertise includes embedded hardware design (microcontroller & microprocessor-based systems), high-speed and low-power PCB design, RF and antenna tuning, BLE/Wi-Fi/LoRa/GSM connectivity, and EMI/EMC-driven layouts. I work extensively with interfaces like SPI, I2C, USB, CAN, RS-485, Ethernet, and storage technologies including DDR, eMMC, and NAND Flash. I have hands-on experience with tools such as Altium Designer, KiCAD, OrCAD/Allegro, LTSpice, and industry lab equipment including VNA, spectrum analyzers, and oscilloscopes. On the firmware side, I work with Embedded C/C++, Python, and RTOS-based systems. Beyond design, I focus on DFM, BOM optimization, supply chain coordination, regulatory readiness (FCC/CE), test fixture development, and production support — ensuring smooth transition from prototype to mass manufacturing. I have delivered solutions including: • Custom carrier boards (Raspberry Pi CM4-based platforms) • System-on-Module designs (NXP i.MX6) • Ultra-low-power LoRa + BLE asset trackers • IoT devices for healthcare, industrial, and smart infrastructure applications I follow a structured, risk-aware, process-driven approach with strong emphasis on quality, transparency, and long-term partnership. If you are looking for a dependable electronics engineer who can take ownership of your product — from schematic to production — let’s connect. menos -
