Rotich Caren
@rotichcaren
AI training and data annotation freelancer building ML-backed tools and quality-rated datasets across platforms, plus Business Central development.
KenyaWhat I'm looking for
I do AI training and data annotation across micro1, OneForma, CrowdGen, and AfterQuery, using tools like Labelbox and Prodigy to keep labeled datasets accurate against detailed guidelines. I’ve also rated search quality and reviewed AI model outputs using rubric-based evaluation, with written feedback to support fine-tuning.
Beyond labeling, I build code and pipelines: I shipped backend and frontend work as a Software Engineer Intern, set up Dockerized environments, and built a live network packet analyzer using a PyTorch classifier exposed through a Flask interface. Now I’m developing and customizing Microsoft Dynamics 365 Business Central/NAV solutions while continuing my engineering-and-ML work.
