Freelancer Overview

As a Certified Quality Assurance Engineer /Tester for Testlio, I have handled AI digital product testing for various Websites, web apps, and AI-enabled browsers. My work involves the validation of AI-driven features such as chatbots, recommendation engines, and automation workflows, ensuring they behave accurately, consistently, and ethically for end users. I execute detailed test cases and perform various forms of exploratory testing around AI edge cases and document the various defects clearly to support fast and high-quality resolutions. I am very comfortable working with dynamic, data-driven systems while teaming with developers and product managers to refine AI behavior based on real user scenarios for both Happy Path Testing and Edge Case Testing. My experience strengthens my ability to test complex AI integrations, identify subtle UI/UX issues, and help teams release reliable and user-centric AI products at scale.

Introduction to Testing AI-Powered Systems (Signed NDA not to mention Company Name but AI Training for a AI Enabled Browser)

TextPrompt Response Writing SFT
On a Project dealing with an AI-enabled browser (signed NDA to not reveal company name), I am still involved in the end to end AI feature training and testing for an AI-powered browser assistant. My responsibilities include reviewing and labeling user-AI interaction logs, annotating intents and entities, tagging both correct and incorrect responses, and classifying edge cases to improve the model accuracy and safety. I also evaluate and refine prompt/response pairs for clarity, adherence to product guidelines, and relevance. This ongoing project covers thousands of conversation samples across multiple use cases and continues to expand, requiring high - volume labeling within tight timelines. I follow strict quality standards using detailed labeling guidelines, performing cross-checks and peer reviews, maintaining high inter-annotator agreement scores, and reporting ambiguities not limited to only text data type but images and audio as well for guideline updates, while collaborating with QA leads and developers to validate AI behaviour and ensure model updates are thoroughly tested before release.
