What I'm looking for

I seek a collaborative, AI-focused role where I can apply annotation, data cleaning, and Python skills to improve model accuracy, grow technically, and deliver high-quality datasets.

I am a detail-oriented data analyst with a B.Sc. in Data Analysis and hands-on experience training and improving AI systems through annotation, transcription, and dataset management. At Execo AI and Samasource AI, I labeled large datasets, conducted audio/video transcription, validated and cleaned data, and collaborated with engineers to deliver high-accuracy results under tight deadlines.

I use Python, SQL, Excel and labeling tools to prepare and manage datasets, run quality assurance, and provide structured feedback during model testing. I am passionate about leveraging analytical skills to optimize datasets, enhance machine learning performance, and contribute to data-driven product improvements.
