AI Trainer focused on video annotation and data labeling, with a PostgreSQL data-quality capstone and prompt-engineered AI workflows.

Kenya

Message

I built the Soko Fresh Mart PostgreSQL data-quality capstone as a Kenyan supermarket dataset seeded with duplicates, nulls, referential-integrity breaks, and inconsistent formatting. I designed and ran QA checks to detect, document, and resolve the seeded issues, then packaged the work as a documented, reusable open-source template.

In freelance AI workflow automation, I designed and deployed an 8-node pipeline using WhatsApp intake, OpenAI qualification logic, conditional branching, and logging. I tested and refined prompts against real user inputs to improve consistency and reduce ambiguity.

I'm currently completing the Commonwealth Bank Introduction to Data Science job simulation, categorizing, tagging, and validating spreadsheet datasets. I also practice timestamp-based transcription with TranscribeMe and am studying Computer Science at Jomo Kenyatta University of Agriculture and Technology.
