Moffat Maina

I’m a Freelance Programmer and AI Specialist with a BSc in ICT, focused on building accurate, safe AI through strong data practices. My work blends AI training (RLHF), machine learning, and data analytics to turn raw information into reliable outcomes.

In my current role as an AI Trainer (Outlier), I fine-tune LLMs using RLHF to improve both accuracy and safety. I also debug and audit Python/JavaScript code, then use linguistic analysis to raise the quality of AI responses.

Previously, as a Data Analyst & ML Developer (Freelance), I built automated data pipelines and dashboards and developed machine learning models that delivered +35% efficiency. I focused on delivering customer intelligence insights that support better decisions.

My foundation includes Technical Data Annotation (Appen), where I annotated NLP and speech-recognition datasets, performed transcription and QA, and evaluated search relevance and user intent. I bring a careful, quality-first mindset—because good data directly determines great AI.
