Worked on the strata-org/Strata repository to deliver formal verification proofs for call-elimination and deterministic-to-nondeterministic transformations in Boogie-based programs. Applied formal verification and theorem proving techniques using Lean to ensure semantic preservation and correctness of automated compiler transformations. Addressed and corrected multiple errors in the nondeterministic transformation proof, updating the SemanticsProps.lean file to improve reliability and coverage. This work enhanced the verification framework, reducing transformation risk and supporting safer refactoring and optimization pipelines. Leveraged expertise in static analysis and compiler transformations to increase confidence in automated processes and minimize regression risk within the Strata codebase.
