What I'm looking for

I’m open to remote and freelance opportunities in data annotation, AI evaluation, and quality assurance, where I can contribute reliable work and collaborate with teams that value clear communication and accuracy.

At micro1 and e2f, I contribute to remote annotation projects, working with transcription, translation, semantic analysis, and language data for LLM and NLP projects. I focus on applying quality standards and preserving meaning in annotated content.

At SportAI, I annotated racket sports data for computer vision projects and reviewed annotations to support dataset quality. I’ve also worked on AI-focused software development and annotation quality assurance at Talent Africa.

I hold a Diploma in Software Engineering and use tools including CVAT, Label Studio, Labelbox, and Python in my annotation work. I’m open to remote and freelance opportunities in data annotation, AI evaluation, and quality assurance.
