What I'm looking for

I’m looking for remote work where I can apply my data annotation and LLM evaluation skills to deliver measurable accuracy, plus transcription, virtual assistance, and SEO content support—while continuing to grow my front-end skills with React.

I’m a detail-oriented and adaptable freelancer with 4+ years of experience across major platforms, including Upwork, Fiverr, Clickworker, and OneForma. I deliver transcription, annotation, and LLM moderation tasks with strong accuracy—achieving 98%+ accuracy in audio annotation on OneForma—and I’m known for reliability, maintaining a 5-star rating on Upwork.

I also support virtual assistance, internet research, product testing, and review writing, while producing SEO-optimized content and completing data-entry assignments. Beyond my core work in data annotation and LLM evaluation (text, audio, sentiment, tone), I’m building a stronger front-end foundation in HTML, CSS, JavaScript, and React, supported by ongoing online certifications and continuous improvement.
