Built a Python analysis and visualization tool, developed with Cursor and Claude Code, that pulls device repair data from the iFixit API and scores it on repair steps, tools required, and fastener types. Applied it across a decade of iPhone, Samsung Galaxy S, and Google Pixel models, benchmarked against the Fairphone.

Found that smartphone repairability declined sharply through the mid-2010s, largely as a consequence of adding water resistance, then recovered after 2020 under regulatory pressure and the Right-to-Repair movement. The resulting fastener and tool-selection insights give designers a historical basis for building more repairable devices.

As a research assistant in UC Irvine's Department of Radiological Sciences, used SolidWorks to design, prototype, and 3D-print the tools for breaking open quartz vials of radioactive powder, working across FDM, SLA, and SLS processes.

Prototyped a zero-radiation-exposure syringe for mixing the bone cement without exposing the user to the radionuclide, designed for injection-molding production.

Developed C++ firmware and Wi-Fi browser controls to operate the vehicle's drive modes from a smartphone, and to automatically cut motor power when an obstacle was detected within the braking threshold.

Integrated and tested the complete hardware/software system, demonstrating autonomous emergency braking during full-throttle obstacle-approach tests. Designed as a proof of concept for compact active-safety features, with accelerometer-based anti-lock braking identified as a future extension.
