What I'm looking for

I'm looking to test complex, high-load products where I can combine manual and API testing, Python automation, and domain-driven validation while growing in C++ and ML-integrated engineering.

At Rock Flow Dynamics, I tested tNavigator, industrial software for reservoir simulation and oil-field development planning. I rolled out commercial module functionality across 10 enterprise customer environments with no critical post-release incidents.

I designed a scalable strategy covering about 80% of a core module through 1,000+ functional, integration, and regression test cases. Over three years, I identified and tracked about 1,000 defects, including around 200 critical or blocker issues.

I validate REST APIs with Postman, analyze client-server behavior in DevTools, and automate data checks with Python. I’ve also tested an AI agent for response consistency, physics accuracy, and edge cases, and investigated C++ memory, concurrency, and execution issues using sanitizers, Valgrind, and Linux tools.

My petroleum engineering background helps me build hydrodynamic models and test fluid-dynamics scenarios realistically. I also developed an ML surrogate model for reservoir history matching and mentored three QA/RE engineers on product internals, testing processes, and modeling standards.
