Freelancer Overview

I am a freelancer who has worked with several testing companies that work with AI training companies. These testing companies include Applause Testing Company, Tester Work, Testlio, RWS, and Telus International. I have been able to work on projects under Multimango and Parimango, among other AI training projects. I have also constantly gone through online learning classes to boost my skills in the machine learning programs. In Applause, I have worked on machine learning projects under Google, feeding the AI model with human behavioural characteristics, as well as face recognition under different disguises. I have also worked on translation projects, assessing the AI translation input from English to Swahili, as well as image labelling of different elements. I have also assessed AI outputs from AI-generated images and videos, identifying the errors and unrealistic outputs.
