What I'm looking for

I seek roles in AI annotation or content writing where I can apply attention to detail, meet strict deadlines, work with clear guidelines, and contribute to quality-driven teams.

I am an experienced annotator and content writer with a strong background in AI training, data collection, and producing timely, high-quality content that adheres strictly to client instructions. I bring a meticulous eye for detail and a track record of meeting deadlines with zero delayed submissions.

Previously I worked across roles in content writing and banking operations, where I led teams, exceeded CASA and branch targets, reduced loan defaults, and earned recognition such as employee of the month. My content work was regularly rated five-star by clients between 2018 and 2021, and I continue to apply those standards to AI annotation tasks.

I value accuracy, reliability, and client satisfaction, and I seek opportunities where I can contribute to AI training projects or content teams that prioritize quality, clear guidelines, and measurable outcomes.
