Leading chaos testing and consistency validation strategy for YugabyteDB's transactional, resiliency, and optimizer layers. Built and maintain original tooling for query optimizer benchmarking, randomized query generation, and differential testing that compares YugabyteDB vs PostgreSQL behavior under fault conditions. Designed Jepsen-based consistency scenarios that surface edge cases across distributed environments. Driving AI-augmented testing initiatives including automated failure analysis and AI coding agent benchmarks, and mentoring engineers on QA tooling and methodology.

Built and maintained original tooling for query optimizer benchmarking, randomized query generation, and differential testing comparing YugabyteDB vs PostgreSQL behavior under fault conditions. Designed Jepsen-based consistency scenarios across transactional, resiliency, and optimizer layers.

Built and maintained Jepsen-based consistency scenarios for a distributed RDBMS. Developed test frameworks and SQL test utilities from scratch, implemented user scenario coverage across the QA infrastructure, and maintained CI pipelines for test execution and reporting.

Designed and maintained test frameworks for both local and distributed environments across Apache Ignite releases. Built a Python-Java toolset for functional and performance validation, and led a full redesign of the distributed Java stability testing framework. Covered new features end-to-end from code review and acceptance criteria through automated test implementation.
