Running a temporary lower billing rate as I launch on this platform. Hi, I’m am an American U.S. based medical device engineer with 15+ years of experience designing, testing, and validating PCB-level electronics for medical, industrial, military, and R&D applications. I specialize in EagleCAD/Fusion360 (primary) and Altium-compatible designs, and have hands-on experience with micro-soldering and bench-level troubleshooting and repair (facilities can be arranged for the right project). If you need help turning a schematic into a manufacturable board, debugging an existing design, or setting up automated testing for your hardware, I can support you from system concept through prototype, verification, and market release. Transparent communication and regulatory-grade documentation come standard—you’ll always know what’s been done, what’s next, and why it matters. Let’s get your design validated and ready to build.

I help companies design, prototype, and troubleshoot complex hardware systems, especially where mechanical, electrical, thermal, and control systems must work together reliably in demanding real-world environments. I am a former Head of R&D at Northrop Grumman Marine Systems, with experience in turbines, generators, electric motors, rotating machinery, and large-scale power systems. My work also includes combustion systems, battery systems, power electronics, embedded hardware, and full product development from concept through working prototype. I work with startups and established companies on: - hardware system design - rotating machinery and power systems - combustion, thermal, and fluid systems - battery and embedded hardware - controls, instrumentation, and industrial automation - diagnosing and solving difficult engineering problems I focus on practical, buildable solutions with strong attention to reliability, manufacturability, safety, and system integration. I’m often brought in when a project needs senior-level engineering direction to move from concept to a working system efficiently. I studied engineering and business at Stanford University and have 20+ years of experience working with venture-backed startups, helping connect engineering decisions to product development, scaling, and execution.

I am a Senior Electrical Engineer with a Master’s degree and 16 years of experience designing embedded electronic systems from concept through production. My work includes electronics architecture, schematic design, PCB layout, firmware development, server-side system integration, and prototype bring-up for low-volume and production hardware. I have extensive experience with PCB design and manufacturing, including over 10 years using Altium Designer, along with Eagle, KiCad, and other professional tools. My designs account for signal integrity, power integrity, EMC considerations, and manufacturability. I regularly support projects through prototype builds, validation, and transition to contract manufacturing. My technical background includes a wide range of sensors and subsystems such as temperature, humidity, time-of-flight, reflective sensors, load cells, RTDs, pressure sensors, light sensors, smoke detection, IMUs, magnetic sensors, mmWave radar, GPS, and image sensors. I design complete systems that integrate sensing, processing, power management, communications, and backend connectivity. I have developed designs involving bidirectional motor control, piezo mist drivers, servos, heaters, LED drivers, PMICs, battery charging and protection, audio systems with mixing and noise cancellation, RFID and NFC, AC-powered systems, switch-mode power supplies, vision systems, and closed-loop temperature control using PID. My embedded software experience includes bare-metal and RTOS-based development across a wide range of platforms, including PIC, AVR, SAMD and SAMG, STM32, nRF52, EFM32, MSP430, PSoC, LPC, Kinetis, i.MX, Jetson, and Raspberry Pi. I work with Microchip, Atmel, Nordic, ST, Silicon Labs, and Espressif toolchains, as well as FreeRTOS, uC/OS-III, Zephyr, and FPGA-based systems. I have significant experience with IoT system integration beyond the device level. This includes server-side communication protocols for connected products, backend services, databases, and client-facing applications. I have worked with REST APIs, MQTT, WebSockets, TCP/UDP, and custom protocols, using Python and Node.js on the server side, along with SQL and PostgreSQL databases. I have also developed web-based client portals using React and Bootstrap to support device management, data visualization, and system administration. Separately, I use Python extensively as a development and engineering tool. This includes writing scripts and utilities for automation, testing, debugging, manufacturing support, data analysis, and workflow integration during hardware and firmware development. I have designed wireless and connected products using ESP32 and ESP8266, nRF52, u-blox cellular modules, LoRa, Zigbee, and Z-Wave. These systems have been deployed across consumer, industrial, automotive, marine, aviation, and agricultural applications. Industry experience includes RV systems, drones, consumer electronics, industrial equipment, automotive lighting and heating, marine wireless sensor networks, aviation seat and heater controls, and agricultural equipment. I am comfortable working with both startups and established manufacturers and understand the tradeoffs required to move a design from prototype to production. I focus on building reliable, manufacturable systems and communicating clearly throughout the project. If you need an engineer who can own the hardware, firmware, and system integration end to end, I am ready to help.
