What I'm looking for

I'm looking for opportunities to evaluate and improve AI systems through RLHF, multilingual annotation, prompt analysis, and responsible AI practices, while contributing to safer, more accurate, and better-aligned language models.

I've evaluated 1,000+ AI-generated conversations, using RLHF rubrics to assess correctness, helpfulness, coherence, safety, and relevance. Through freelance AI/RLHF projects, I provide structured feedback that improves response quality and user alignment.

I annotate datasets, compare and rank model outputs, and identify recurring issues including hallucinations, factual errors, and tone inconsistencies. I also conduct English–Swahili linguistic analysis and translation-quality reviews under strict guidelines.

Alongside AI evaluation, I edit academic, technical, and business documents for clarity, grammar, consistency, readability, and formatting. I'm committed to responsible AI development, model alignment, and continuous learning in NLP and large language models.
