Hi there! I'm Brett Hartman, a dedicated Multimodal AI Quality Specialist based in Honolulu, Hawaii. With 15 months of focused experience in high-precision data annotation, generative AI evaluation, and quality assurance, I blend a linguistics foundation (TESOL/ESL), critical listening, and operational excellence to deliver reliable, high-precision results across audio, text, image, and video tasks. I am committed to continuous learning and eager to contribute analytical skills to a team building robust AI models. I also bring a creative edge as a professional vocalist, songwriter, and musician, which informs my approach to AI audio and TTS evaluation and grounds QA rubrics in real-world user experience. I look forward to applying my skills in a collaborative environment that values accuracy, clarity, and scalable processes.
