PROFILE

Mikhail R. Gadelha

Over two months, contributed to the esbmc/esbmc repository by developing and optimizing advanced program verification features for C and C++ codebases. Focused on enhancing termination analysis, symbolic execution, and concurrency modeling, the work introduced interval-based k-induction, ranking-function checkers, and memory optimizations that improved both soundness and performance. Leveraging C++, Python, and Bash, implemented deterministic build processes, streamlined CI/CD workflows, and refactored core data structures for maintainability and reliability. The engineering approach emphasized formal verification, static analysis, and algorithmic efficiency, resulting in faster verification feedback, improved SV-COMP readiness, and a more robust foundation for scalable software analysis.

May 2026 monthly summary for esbmc/esbmc focused on delivering stronger termination guarantees, sound pointer handling in k-induction, and developer-ops improvements to CI and build hygiene. Major investments in the k-induction and interval-analysis pipeline improved both soundness and performance, particularly around pointers and inductive steps. Concurrency modeling was stabilized through refactors, enabling more reliable analysis of multi-threaded code. Business value was unlocked via more accurate termination proofs (SV-COMP improvements) and reduced CI waste through automation.
