What I'm looking for

I’m looking for a high-impact QA role where I can combine traditional web/mobile testing with generative AI and multimodal evaluation—using hallucination detection, RLHF, and rigorous QA to improve accuracy, safety, and user experience.

I’m an experienced, detail-oriented Senior QA Analyst with 10+ years of hands-on experience in quality processes across startups and large organizations. I currently specialize in Generative AI and Multimodal Evaluation, applying rigorous QA methodologies to fine-tune Large Language Models (LLMs) and visual synthesis systems.

I’m known for manual software testing for web and mobile, test planning, and functional testing, with deep expertise in identifying model hallucinations, ensuring aesthetic alignment, and performing RLHF to improve accuracy and safety. Using a user-centered, precision-first approach, I bridge traditional software quality with the evolving field of Artificial Intelligence, and I’m actively seeking to leverage this dual expertise in a high-impact QA role.
