AI & geospatial data labeling specialist driving high-quality datasets for computer vision.
What I'm looking for
I am an AI data labeling and geospatial specialist with over five years of remote experience creating high-quality datasets for computer vision, NLP, and geospatial models. I deliver structured annotations and rigorous QA to help train accurate, high-performance AI systems.
I have worked across renewable energy, construction monitoring, marine systems, and multimodal dataset projects, using tools such as Labelbox, CVAT, Supervisely, Hasty AI, and QGIS. I routinely validate automated outputs and refine labeling standards with ML teams.
My services extend beyond annotation to include transcription, translation (English/Kiswahili), prompt testing, LLM evaluation, data management, and workflow automation using Make.com and Zapier. I combine a process-driven mindset with strong communication to ensure project consistency and timely delivery.
I am pursuing a Bachelor of Education (Technology Education) at Moi University (expected Dec 2025) and hold certifications in data annotation and prompt engineering. I am open to remote roles compatible with EMEA timezones and focused on impactful AI and geospatial projects.
