Hello, I'm
Harmanpreet Singh Sagar
Software Engineering student at McMaster with a habit of working closest to wherever the interesting problem is, whether that is firmware, backend systems, or anywhere in between.
About Me
Software Engineering student at McMaster University (Class of 2027) who has verified SERDES designs in C++, written firmware for satellite subsystems in Embedded C, and led the architecture and development of a full-stack IoT platform. I like working on problems where the software and the system are equally important.
