I help businesses, creators, and AI teams transform raw audio, video, images, and text into accurate, structured, and valuable outputs.
With 4+ years of professional transcription experience and 3+ years supporting AI training and data annotation projects, I deliver work that is accurate, consistent, and ready for use. From complex medical discussions to AI model evaluation, I focus on quality, clarity, and attention to detail.
For more than four years, I supported an international cancer education organization, producing accurate transcripts for expert interviews, webinars, lectures, and member Q&A sessions. That long-term partnership grew into more than transcription. I also created timestamped summaries, resource lists, and other content that helped make complex medical information easier to understand and use.
Here's how I can help:
✔ Transcription
I produce clean, well-formatted transcripts for podcasts, interviews, webinars, meetings, courses, and other recorded conversations. I am comfortable working with technical and medical content, multiple speakers, and recordings that require careful research and quality checks.
✔ AI Data Annotation
I support AI training projects through prompt evaluation, response ranking, prompt development, image and audio annotation, transcription quality assurance, data verification, and other structured annotation tasks that improve model performance and data quality.
✔ Content Repurposing
I help podcasters, YouTubers, course creators, coaches, educators, and businesses get more value from every recording. I turn podcasts, interviews, webinars, courses, meetings, and presentations into polished content such as show notes, summaries, key takeaways, blog articles, newsletters, social media posts, chapter titles, timestamps, YouTube descriptions, and course materials.
Tools I regularly work with include Whisper, Descript, Otter, Microsoft Word, Google Docs, ChatGPT, Claude, Gemini, and AI data annotation platforms such as Appen and Outlier.
If you need accurate transcription, reliable AI data annotation, or content that extends the value of your recordings, I'd be happy to discuss your project.
