TestMu AI Author

Parth Mistry is a Member of Technical Staff at TestMu AI (formerly LambdaTest), building SmartUI, the visual regression testing product. He developed and owns the SmartUI CLI, a modular TypeScript tool built on Playwright for multi-browser automation, and built the Storybook CLI for visual regression of UI components. He maintains cross-language SDKs in Python, Java, Ruby, C#, and Node.js, and engineered a Node-based visual rendering service on Kafka, Redis, MySQL, and S3.

His migration of that service to an event-driven, KEDA-autoscaled architecture improved execution speed by 60% and cut annual infrastructure cost by $9,600. He also built the end-to-end SmartUI integration with KaneAI. Parth is a Google Summer of Code 2024 contributor and an alumnus of IIT Jodhpur.
