What I'm looking for

I seek roles focused on data annotation and QA in collaborative, agile teams where I can improve AI/ML datasets, localization, and user experience.

I am a tech-savvy BSc Computer Science graduate experienced in large-scale data annotation, collection, and quality assurance testing for web and mobile platforms. I have annotated over 500,000 images and text entries, reported 100+ bugs, and contributed to localization and UX improvements across projects in East Africa.

I thrive in fast-paced, collaborative environments and apply agile methodologies and tools like Jira, Postman, TestRail, Android Studio, Trello, KoboToolbox and ODK to deliver accurate, culturally aware datasets and reliable QA documentation. My background includes government internship experience and hands-on projects in app localization and urban planning data collection.
