Key Challenges
- Designing syntax and grammar
- Building a parser and interpreter
- Error handling and debugging
Key Learnings
- Compiler fundamentals
- Abstract Syntax Trees
- Language runtime design
Overview
In this project, I built a programming language from scratch to understand how real languages work internally.
The goal was not performance, but clarity.
What I Built
- Lexer
- Parser
- Abstract Syntax Tree (AST)
- Interpreter
Key Concepts Learned
- How source code becomes executable
- Syntax vs semantics
- Runtime environments
- Error reporting
Why I Built This
Understanding how languages work internally makes you a much better backend engineer — especially when debugging, optimizing, or designing systems.
