What I'm looking for

I seek roles applying my microbiology and AI data-training experience to improve model quality and deliver measurable organizational impact, with opportunities for skill growth.

I am a BSc Microbiology and Biotechnology graduate with hands-on experience preparing and curating data to improve AI performance. I combine scientific training with practical data work to produce reliable, domain-informed datasets.

I have trained models and written nonfiction essays for model instruction at Mindrift AI and Toloka, performed data loading and annotation at Samasource, and transcribed audio for Verbit. I developed dialogue prompts and curated conversation datasets focused on microbiology and biotechnology topics.

I bring strong attention to detail, proven administrative and logistics experience from roles at Jumia and Kenyatta University, and a commitment to improving model accuracy and organizational efficiency through careful data work.
