Bit Twiddler

Definitions

1. A programmer who is skilled at or obsessed with low-level manipulation of bits, masks, shifts, and binary representations, often in embedded, systems, or performance-sensitive code. The term is usually admiring but can also imply overfocus on low-level cleverness.

   In plain English: Someone who is especially comfortable working with low-level binary operations in code.

   Example: "You need a real bit twiddler to explain why that checksum routine is branchless and still readable."
