I help businesses translate complex datasets into structured, decision-ready insights that improve clarity and support confident action. With a background in English language work, including proofreading, transcription, and AI training for large language models, I developed advanced capability in working with high-volume, detail-intensive information. This work required strict accuracy control, consistency validation, and structured evaluation of outputs, forming a strong foundation in data quality, logic, and analytical thinking. This naturally led into data analytics, where I work with Excel, SQL, and Power BI to transform raw datasets into validated structures, meaningful patterns, and clear analytical outputs. I specialise in data preparation, transformation, and analysis, with a focus on ensuring integrity from raw input through to final reporting. I deliver analysis and reporting that is precise, structured, and aligned to business decision-making. My work prioritises data integrity, analytical clarity, and consistency across every stage of the data lifecycle.
