What I did
Designed low-cost, highly scalable analog and digital Quad Sun Sensor (QSS) circuits for LEO satellites, cutting unit cost ~70% versus the existing product line while preserving flight performance.
Achieved first-spin hardware success by owning the full design cycle: schematic capture, layout, embedded firmware, and hardware validation.
Developed Python/C++ calibration algorithms and mathematical models converting quadrant photodiode response into precise sun angles, improving effective sensor accuracy by 250%.
Authored space-grade engineering documentation — part stress, reliability, derating, and thermal analyses — to flight-program standards.
