At the Kenya National Bureau of Statistics, I conducted 1,200+ household interviews for the Kenya Integrated Household Budget Survey using KoboCollect, ODK and SurveyCTO. Field-level quality checks helped reduce errors by 20%.
At Invisible Technologies, I validated and quality-checked 100,000+ records for AI/ML training datasets. I also supported RLHF, SFT, annotation and evaluation workflows, and built data-quality dashboards using Power BI, Excel, Python, SQL and R.
For the Kenya National Bureau of Statistics census, I supervised and supported 40+ enumerators, achieving 98% data accuracy through field verification and monitoring. I also bring experience in banking operations, transaction verification and financial reconciliations.
