Freelancer Overview

I bring robust expertise in data integrity and digital annotation tools, having handled extensive verification and structured recording workflows for international research bodies like IFPRI, SAFE Africa, and CIMMYT. I am highly proficient in navigating digital questionnaire databases and mobile platforms like Survey-CTO, where I have mastered executing complex logic guidelines, data validation, and strict data quality checks. My project work includes managing data collection pipelines for large-scale baseline studies and conducting technical field evaluations for mobile applications. Beyond my technical skills in data cleaning, anomaly detection, and verification, my background as a university Electoral Commissioner highlights my exceptional adherence to strict protocols, data security, and zero-error quality standards. Combined with an advanced command of English, I am uniquely equipped to evaluate, refine, and build high-quality datasets.
