Key Skills

Freelancer Overview

I have hands‑on experience producing and quality‑checking data for AI‑related work, mainly through research and analytics projects where I clean, validate, and structure complex datasets using Python, R, and SQL. In my recent roles, I built scripts with Pandas and NumPy to preprocess multi‑source data, ran systematic checks to catch inconsistencies, and maintained accurate databases with thousands of records, which closely mirrors the rigor needed for reliable AI training data. I also design and follow structured workflows and tests, from forecasting models to environmental and public‑health analyses, and I use prompt‑engineering techniques to guide AI models and probe their behavior, helping me think like both an annotator and an evaluator. This combination of data‑cleaning, QA mindset, and practical experience steering AI via prompts makes me well suited for data labeling, AI training, and expert evaluation tasks.
