Compiler Project at Custom Programming Language and Compiler

Engineered a full compiler for Bluejay, a custom C-like language, using Flex for lexical analysis, Yacc for parsing, and AST generation. Performed semantic analysis with type checking and lexical scoping, and translated the AST to an intermediate representation and compiled to MIPS assembly using a stack machine.
