Lead Compiler Developer at Aztec
Chicago, Illinois, United States
Summary
🤩
Rockstar🎓
Top SchoolJake Fecher is a Lead Compiler Developer based in Chicago with a decade of experience building language tooling and compilers. He created the Ante programming language and drives compiler work at Aztec, bringing practical systems-language design to zero-knowledge and blockchain-adjacent domains. His open-source work includes substantial parser and type-checking rewrites—notably improving the Noir language parser for ZK proofs and implementing lexer, parser, and expression evaluation for Ante. Jake blends academic CS foundations from Northeastern with hands-on backend engineering, favoring parser combinators and clean type systems to reduce complexity and eliminate dead code.

Role in this project:
Back-end Developer
Back-end DeveloperContributions:1 release, 3265 reviews, 400 commits in 1 year
Contributions summary:Jake primarily focused on modifying the parser for the Noir language. They rewrote the parser using parser combinators and implemented the parsing of structs, thereby extending the language's functionality. In addition, the user made significant changes to the type-checking component, including type checking if statements, thereby improving the type system's accuracy. Furthermore, the user removed unused code such as predicate expression nodes.

Contributions summary:Jake primarily worked on the development of the Ante language's parser and related components. They implemented and updated the parser functionality, including handling variable definition, function calls, and infix expressions. The contributions also include defining tokens, creating a lexer, and making modifications to both the parser and expression evaluation components of the language, ultimately leading to a more complete and functional implementation.
