Khushaan Virk

Electrical Engineering at UBC (BASc, expected 2028). I build embedded and hardware systems, and the software that makes them measurable.

Right now I'm a Software Engineer at Advizr, shipping Python/FastAPI backends and automation pipelines for client systems in production. Before that, most of my work has been closer to the silicon: STM32 and 8051 firmware, discrete MOSFET motor drivers, analog signal conditioning, and a 4-layer PCB I took all the way through fab, assembly and bring-up.

The thread through all of it is pulling a trustworthy signal out of a noisy physical system, then proving how well it actually worked.

Looking for: an engineering co-op in embedded, firmware, hardware, or systems software.

Selected work

Pedestrian Dead Reckoning · Python, NumPy, SciPy Reconstructing a walked path from a phone's accelerometer and gyroscope alone, then measuring how far inertial drift pushes it off a known 76.2 m route. Band-pass step detection, gyro bias correction, and loop-closure error measurement. 5.14 m of drift (6.7%), validated across two runs with a held-out parameter check. Both raw recordings are in the repo, so every number reproduces.

khushaanvirk.com · Next.js, React, TypeScript My portfolio, built as a content-driven system: every project is a typed data object rendered by shared components, statically generated so a malformed entry fails the build rather than the page.

65% Mechanical Keyboard PCB · Altium, STM32, bare-metal C 67-key hot-swap board. STM32F072 with crystal-less USB, 4-layer stackup, 90 Ω USB differential pair computed by hand from the real prepreg geometry. Fabbed and assembled at JLCPCB, worked on the first spin, and it is the board I type on. Bare-metal USB HID firmware with no HAL and no CubeMX.

Team firmware projects (ELEC 291, teams of 6) Field-following robot. Dual-MCU autonomous robot that tracks a current-carrying wire via LC-tank pickup coils, with optocoupler-isolated H-bridges to keep motor switching noise out of the inductive sensors. Reflow oven controller. Closed-loop thermal control to ±3 °C with a thermocouple front-end and a Python serial DAQ harness for verification.
