At Amazon (Alexa AI), I provided data creation, annotation, transcription, and labelling services across four language locales to train and improve Alexa speech recognition and language understanding models. I also supplied labelled datasets to machine learning science and modelling teams.
I managed an 18-month transcription project as the primary point of contact, coordinating timelines and resources to meet quality and turnaround targets. I trained five new hires for the English UK project, helping achieve a 90% quality rate and a 20% improvement in overall team performance.
At Taronga Conservation Society Australia, I conducted a time-motion study and used SQL analysis to identify process improvements that increased operational efficiency by 15% and saved 10 hours of team time per week. I also built four Power BI dashboards and added MySQL validation constraints to reduce data errors by 10%.
On the Market Insights and Predictive Analytics project, I built a teacher supply forecasting model that achieved 98% accuracy. I also analyzed retail support tickets and created a Tableau dashboard to help stakeholders explore repeat visits and assess a proposed knowledge base rollout.
