What I'm looking for

I seek roles in AI data annotation or localization that value accuracy, cultural nuance, timely delivery, and opportunities to expand my technical impact.

I am a Food Science graduate who merges scientific rigor with hands-on experience in data annotation, localization, and AI training. I have completed projects for Uber AI, Crowdgen by Appen, Neon Mobile, and freelance clients on Upwork, delivering high-quality translations, audio annotations, chat-testing feedback, and precise data labeling that improved model performance.

My background includes laboratory experience in physiochemical and microbiological testing, strong research and Microsoft Office skills, and fluency in English, Igbo, Hausa, Yoruba, and French. I prioritize accuracy, cultural nuance, and timely delivery, and I seek roles that let me apply my bilingual skills and technical annotation experience while continuing to grow in AI data work.
