What I'm looking for

I am looking for a role that allows me to provide high-value AI training & annotations, data entry and reporting support while continuing to grow into business analytics.

I turn data into insights, AI into accuracy, and lessons into measurable results.

I’m an AI Training Data Specialist, Data Analyst, Test Prep Instructor, and CX & Business Operations professional who thrives at the intersection of data, AI, and real-world impact. I help organizations make smarter decisions, build AI systems that understand culture and language, and guide learners to achieve their goals.

In AI and NLP, I annotate, and evaluate machine learning datasets, with a focus on English–Hausa localization. I ensure data is accurate, culturally relevant, and consistent, helping AI systems communicate naturally and effectively while reducing errors by 40%.

In analytics, I use SQL, Excel, and Power BI to transform raw data into actionable insights. I’ve built dashboards that improved business visibility by 25% and streamlined reporting, helping teams make faster, better decision

I also bring my experience as a GRE (Verbal) , SAT (R&W), and IELTS instructor to every role. Designing structured, data-driven lessons has sharpened my ability to break down complex concepts and communicate clearly—a skill I use to make technical insights accessible to stakeholders.

I’m passionate about opportunities where data, AI, and cross-cultural expertise converge, and I love helping organizations and learners achieve tangible, measurable results.
