Contributed to the informalsystems/quint repository by building and refining core backend and simulation infrastructure, focusing on scalable verification and robust state evaluation. Leveraged Rust and TypeScript to implement features such as seed-based reproducibility, ITF trace output, and cross-language witness tracking, while enhancing error handling and type safety. Improved testing reliability through integration of CI workflows, expanded test coverage, and deterministic sampling. Refactored interfaces and workflows to support large-scale powerset sampling using BigInt, and maintained code quality with consistent formatting, linting, and documentation updates. The work emphasized maintainability, parallelism, and correctness across backend, CLI, and simulation components.
