I help engineering teams find the failure modes their tests weren't designed to catch. The same technique used internally at AWS, Oracle, and Microsoft; made practical for teams building complex stateful systems (distributed protocols, cloud-native architectures, payment infrastructure) who need or already run fuzzers, chaos injection, or DST.
As AI-generated code reaches production faster than test suites can keep pace, executable specs are one of the few techniques that can keep up. They describe intent precisely enough to test generated code against, and can be invoked by agents as a verification tool at generation time.
Make complex software boring again.

🎯 Test Oracle Design: if your team already runs fuzzers, DST, or property-based testing, I help you design a specification-based oracle that dramatically increases the signal from tools you already have
⚡ Model-Based Adversarial Testing: end-to-end: spec, adversarial test generation via random and symbolic execution, conformance testing against the implementation
🤖 AI-Generated Code Testing: executable specs as precise oracles for LLM-generated protocol code, invokable by agents at generation time
