• Reduced onboard interface error rate by developing an ECSS-compliant interface architecture. • Cut spacecraft parasitic EMI by introducing galvanic isolation and grounding requirements for subsystems derived from ECSS&experiments. • Defined the spacecraft-level electrical ICD. • Eliminated late-stage interface failures (on flight model) by codifying ECSS requirements for the onboard harness into an internal engineering standard. • Cut QA testing time by designing a test PCBs for the incoming QC station.

• Achieved ≤20 mm accuracy of the laser rangefinder by developing STM32F407 DSP brd, 1 ps res TDC, 10 ns GaN laser driver, APD, 300 MHz LNA, power supply. • Ensured a 3°/h FOG stability by developing power supply, TIA, 12/16-bit mixed-signal ADC boards, STM32F429 and Spartan DSP boards (SPI, RS-232, UBS2.0/Ethernet; led embedded software developing), laser driver. • Automated resonator characterisation (6-12× faster) by developing GaN laser driver, 14-bit DAC, LF driver, PIN-pd, LVDS/CML/SE converters.

• Delivered in-house radhard isolated DC/DC converters (33–50 W) into serial production: lead time 12–18 → 1–3 months, ~9× lower cost. • Halved mass & size of a stepper-motor drive by moving it from board level into a hermetical radhard multichip module. • Achieved ASIC SEU immunity via a triple-redundant control FSM with majority voting (Verilog), FPGA-verified. • Reduced testing time 12x by developing embedded software for an STM32F100 logger. • Full-custom layout of PLL and osc on CMOS gate array.
