high-Rel Systems Architecture

Power Electronics & PLM

github.com/wayri

I architect end-to-end hardware systems, engineering the bridge between complex physical domains and reliable control logic.

My foundation is rooted in complete product lifecycle management (PLM), extending from initial design to DFM/DFA, vendor management, and rigorous reliability analysis (FMECA, FMEA, WCCA). I have led the end-to-end Electrical Power System (EPS) subsystem design for satellites and engineered robust Battery Management Systems (BMS) for ground-based energy storage solutions. My expertise also includes designing kilowatt-scale (10kW+) grid-tied inverters for integrating solar PV into the grid, alongside developing critical satellite ground support equipment (EGSE), logging, and protection instrumentation.

My trajectory spans from component-level aerospace hardware and full Hardware-in-the-Loop (HIL) interface development, to creating custom desktop applications for DAQ and load billing, and acting as a technical advisor for projects that directly influence state-level infrastructure and policy.
