JIMOH Sunday Abdullahi
@jimohsundayabdullahi
I evaluate AI outputs and resolve remote IT support issues across cloud, systems, networks, and user environments.
NigeriaWhat I'm looking for
I'm currently annotating and evaluating AI-generated content on HumanSignal, completing around 15 labeling and evaluation tasks daily while maintaining 93–100% Ground Truth accuracy.
Through Mindrift and UHRS, I've evaluated AI responses and search results for accuracy, relevance, factual correctness, and quality. My feedback supports the training and improvement of advanced AI systems.
At M-ADETECH Electrical Ltd, I resolved approximately 20 support tickets each day with same-day turnaround for more than 50 staff. I installed and supported operating systems and office applications while troubleshooting networks, hardware, and software.
I've also provided remote chat and technical support for international users, collaborated across time zones, and moderated online communities. My background includes AWS fundamentals, Windows, Linux, macOS, networking, cybersecurity, and Python.
