Message

At LTK, I replaced legacy manual testing workflows with XCUITest and Pytest automation, helping shorten release cycles from two weeks to one. I also maintained a 500+ TestRail suite and used Postman, Datadog, and SQL to validate features and investigate defects.

At Carnegie Technologies, I tested IoT firmware, gateways, and OTA releases across the data pipeline, checking telemetry persistence from hardware ingestion through to the UI. Earlier, I coordinated QA strategy at JackRabbit Mobile and validated Google and Samsung hardware and software releases.
