PROFILE

Katzper Michno

During a three-month period, Katzper Michno developed and enhanced the mhorod/cacophony compiler, focusing on core areas such as register allocation, memory management, and type safety. Katzper implemented robust name resolution across scopes, improved code generation reliability under register pressure, and introduced escape analysis to optimize memory usage. The work involved deep AST manipulation and traversal, leveraging TypeScript and JavaScript to refactor function declarations, enhance liveness analysis, and ensure correctness through comprehensive testing. By addressing both low-level assembly concerns and high-level language semantics, Katzper delivered features that improved maintainability, performance, and safety, demonstrating strong depth in compiler engineering.
