Profile
I build hardware that has to work in environments where failure is not an option — from liquid rocket engines at 650psi to subsea RF antenna systems to stratospheric payloads. My core strength is systems integration across mechanical, electrical, and software domains: taking a subsystem from requirements to test in the shortest possible time, questioning every inherited assumption along the way.
Currently a Year 1 Electrical Engineering student at NUS. Formerly Aeronautical Engineering (Diploma, GPA 3.75/4.0) at Singapore Polytechnic. Self-taught in liquid propulsion, RF systems integration, FPGA-based signal processing, and embedded systems — not from coursework but from building things and letting reality correct the model.

Projects
SARTS · NUS STAR Centre · Personal
Multi-flight high-altitude balloon programme with entirely self-designed and self-built avionics hardware. Three distinct missions flown to date, each with different RF and systems objectives.
BEAR-11: 7,966m altitude · RTTY/FSK @ 432.600MHz
BEAR-12: WSPR on 20m amateur band · super pressure balloon
BEAR-13: Live video from stratosphere @ 1.28GHz
BEAR-13 (Live Video): Custom 4-layer impedance-controlled PCB designed in KiCad with CPW calculator for GNSS RF frontend bandpass filter. ESP32-based state machine handling RF transceiver operation, battery heater control, and altitude-triggered nichrome wire payload cutter. Link budget validated using RF power meter and calibrated attenuators prior to flight. FM carrier modulated by AFSK audio tones from ESP32 DAC @ 144.390MHz. Independently credited on NUS ECE Department official news page.

Singapore Polytechnic · Volunteer Technical Lead · Self-directed
Self-taught design, fabrication, and hotfire testing of multiple liquid rocket engine variants. Believed to be the only student in Singapore to have independently designed and hotfired liquid engines from scratch. All engines self-funded; all designs originated from first principles rather than copied reference designs.
V1: 550N · 650psi · N₂O/EtOH · Impinging injector
V2: 540N · 400psi · N₂O/IPA · Pintle injector · Design-to-hotfire: 6 months
V3: 600N · Regeneratively cooled · AlSi10Mg additive manufactured chamber
Full test infrastructure designed and built from scratch: pressure feed system (1200psi, 0.3kg/s N₂O), custom DAQ system (432Hz pressure / 10Hz load cell, Python/Linux), torch ignitor, structural test stand. Mentored 12 students across the programme.
