I analyze data and build AI-ready datasets using Python and SQL.
EthiopiaWhat I'm looking for
I'm building practical data analytics and AI experience through freelance annotation, language-data, and analytics projects. I work with English and Amharic datasets, applying careful review, validation, and quality-assurance practices.
In freelance AI data annotation and language specialist work, I transcribe audio, identify speakers, add timestamps, label audio events, and correct AI-generated transcripts. I also support R&D data-labeling projects by categorizing and validating datasets for AI/ML applications.
My projects include e-commerce revenue analysis using SQL, Python, and Tableau, where I prepared data, analyzed customer behavior, and developed dashboards to communicate findings. I've also built a Python and Pandas workflow to clean and validate messy datasets.
I'm continuing to develop in data science, machine learning, NLP, and deep learning through coursework and project work. I enjoy using data to solve practical problems and communicate insights clearly.
