Professional Highlights -NASA: Developed drone detection and tracking systems using Software Defined Radio (SDR) and the Signal Hound API, creating live spectrograms to secure airspace. -Florida Space Institute: Led the research and requirements definition for a 256-element RF survey system with extreme sensitivity (-200 dBm), delivering critical insights to government customers. -NEXT Lab: Prototyped ultrasonic sensors for high-temperature molten salt systems, validating designs for nuclear energy applications. I am available for complex engineering projects that require a deep understanding of electromagnetics, data analysis, and hardware integration. Let's discuss how I can apply this technical expertise to your next project.

I bring over 5 years of hands-on hardware and software design experience, taking projects from initial concept through to a production-ready design (PCB + firmware + connectivity). My PCB design expertise ranges from straightforward 4-layer boards to high-density 10-layer mixed-signal designs that demand tight impedance control, low-noise analog sections, and high-speed digital interfaces (DDR, Ethernet, USB 3.x, etc.). I’m fully proficient in Altium Designer and KiCAD, and I also have solid experience with OrCAD and Cadence Allegro when needed. PCB Design Highlights - Designed and released dozens of 4–10 layer PCBs, including high-speed mixed-signal boards with controlled-impedance traces, differential pairs, length-matched buses, and rigorous power integrity considerations. - Full ownership of the layout process: component placement for optimal signal integrity and manufacturability, stack-up definition, DRC/DFM validation, generation of Gerber, ODB++, and 3D STEP files. - Experienced with HDI features (blind/buried vias, micro-vias) when required for dense 8–10 layer boards. - Strict adherence to IPC standards and specialized requirements (MIL-PRF-31032, NASA-STD-8739.4, EMI/EMC best practices). Embedded Software Development - 5+ years writing production-grade embedded C for a wide range of microcontrollers (STM32, NXP i.MX RT/LPC, Microchip PIC32, etc.). - Linux bring-up and driver work on Raspberry Pi and custom ARM-based SOMs. Automated Test Fixtures & Test Software - Designed and deployed complete electrical/mechanical test fixtures that dramatically improved production throughput and first-pass yield. - Developed desktop test applications in C# (.NET WinForms/WPF) and LabVIEW for functional, in-circuit, and environmental testing. - Authored detailed test procedures meeting military and NASA standards (EMI, shock/vibe, thermal cycling, voltage transients, dielectric withstand, etc.). 3D Modeling & Mechanical Integration - Proficient in Fusion 360 and Solidworks for designing robust, serviceable test fixtures and enclosures. - Seamless electrical-mechanical integration: export of PCB 3D models, collision checks, cable routing, and generation of production-ready drawings. Hands-on Lab & Prototyping Skills - Expert-level soldering (0402, 0.4 mm pitch BGA, QFN) using microscope, hot-air, and reflow stations. - Rapid prototyping and debug with oscilloscopes, logic analyzers, spectrum analyzers, thermal cameras, and environmental chambers.
