Freelancer Overview

I am a Computer Science graduate from Pwani University with extensive experience in the AI data training sector, specializing in high-precision data annotation and Reinforcement Learning from Human Feedback (RLHF). My background includes a three-month tenure with iMerit as a Data Collection Specialist, where I contributed high-quality video data for household task simulations, and various projects involving image labeling, polygon segmentation, and audio-based Elo pair evaluations. I have a proven track record of adhering to strict technical guidelines to support the development of robust machine learning models for platforms like CloudFactory and Telus International. What sets me apart is my technical depth, which combines a solid foundation in computer science with advanced linguistic proficiency in English, Swahili, Luo, and Zulu. This unique combination allows me to handle complex transcription and localization tasks that many data specialists cannot. Furthermore, my commitment to the field is demonstrated by my development of a business plan for a Digital Skills and Job Readiness Center in Kilifi, showcasing my leadership in establishing tech infrastructure and training others in data collection and annotation best practices.
