About Me

▶ Background

I'm a Computer Engineering undergraduate at the National University of Singapore, currently working as an Embedded / SWE at ZeroshotData in San Francisco, where I build robotics software and embedded systems for autonomous navigation and data processing.

My expertise lies in robotics software development, including visual-inertial SLAM (ORB SLAM3), sensor fusion, embedded systems, and real-time pose estimation.

Visiting Student (Exchange)

APR — JUN 2025

▶ WORK AUTHORIZATION INFO

H1B1 (Singapore/Chile): A fast-track alternative to the H1B. Unlike the H1B lottery, H1B1 is quota-based and usually available year-round for Singaporeans as it is historically undersubscribed.

SIMILARITY: Like the TN (Canada/Mexico) and E-3 (Australia) visas, the H1B1 is profession-specific and requires a job offer, but avoids the complex lottery system.

NOTE: These visas are often easier and faster to process than the standard H1B, making it simpler for US employers to hire talent from these specific countries.
