Hi there
I'm Zachary, an AI/ML Data Operations Analyst based in Austin, TX with 7+ years of experience across Apple data operations, annotation QA, and workflow improvement. I build Python and SQL tools, validate high-volume datasets, and ship dashboards that track labeling quality and ML support metrics. If you're interested in the tools and software I use, check out my Tools & Skills.
Previously at Apple, I partnered with global cross-functional teams on Siri NLP annotation pipelines, drove 43% faster escalation resolution, and authored playbooks adopted across multiple teams. I'm always open to hearing about new projects, so feel free to drop me a line.
