Alex Waki

I’m a results-driven AI Trainer and Language Specialist focused on training large language models (LLMs) through data annotation, prompt engineering, and human feedback (RLHF). I bring strong English (Native) and Italian (Proficient) capabilities to every evaluation and annotation task.

I specialize in assessing AI-generated responses for accuracy, clarity, helpfulness, and safety, while also checking cultural nuance and linguistic quality. I work independently in remote, fast-paced environments, and I’m careful about edge cases, guideline adherence, and structured feedback that helps improve model behavior.

In my freelance work (Jan 2024 – Present), I review and rate AI responses across diverse topics, write and refine prompts for training and benchmarking, and produce high-quality Italian-language annotations. Previously, as an Annotation Specialist (Jun 2023 – Dec 2023) I worked on text/audio/video dataset labeling and tagging tasks such as Named Entity Recognition (NER), sentiment analysis, and intent classification, while also evaluating Italian-language search relevance.

As a Content Reviewer & Language Evaluator (Jan 2023 – May 2023), I evaluated search engine results and AI-generated content for relevance, quality, and safety, flagging harmful or misleading outputs and supporting content policy refinement. I’m grounded in my BA in Linguistics & Communication (focus on computational linguistics and language technology) and reinforced by certifications in AI for Everyone, Natural Language Processing, Data Annotation Fundamentals, and Prompt Engineering for Developers.
