INPUT / PROFILE

How I think
and build.

DESIGN NOTE

I design electronics by following the signal all the way through: from the requirement, into the schematic, across the board and onto the oscilloscope. I care about the details that make hardware dependable—clean power, measurable margins and test plans that expose problems early.

01
Situation

The previous controller produced inconsistent braking torque as battery conditions changed.

02
Task

Create a predictable torque request while respecting inverter and battery limits.

03
Action

Modelled the control loop, implemented CAN safety interlocks and tuned gains using track-test data.

04
Result

Recovered 11% more energy per lap with repeatable pedal response.

OUTPUT / 03 VERIFIED
