@mercythiongo
I’m an AI data specialist focused on accurate labeling, verification, and dataset quality.
KenyaWhat I'm looking for
I’m a Computer Science graduate with strong data handling, annotation, and analysis expertise, built through real-world freelance work. I focus on making data reliable for training and improving AI systems through consistent, high-quality outputs.
As a Freelance Data Annotation and AI Support Specialist, I annotate and label text, image, and audio datasets to feed AI models in training. I also perform pairwise comparison to compare and refine AI products, while checking that datasets are very accurate and consistent.
In my previous freelance data work, I gathered, stored, and administered massive amounts of digital data. I kept proper records in Microsoft Excel and Google sheets, cleaned and updated data to eliminate errors and inconsistencies, and supported basic data analysis and report writing.
I’m very precise and structured, able to work remotely and independently, and I adhere to comprehensive project guidelines to ensure data quality. I’m now actively looking for AI Data Specialist opportunities where my attention to detail and commitment to accuracy can strengthen AI systems.
