What I'm looking for

I’m looking for remote work where I can train and improve AI models using accurate data annotation, strict quality evaluation, and performance tuning, while collaborating in distributed teams that value data integrity, reliability, and continuous process improvements.

I’m a detail-oriented Machine Learning Associate with over five years of remote experience delivering high-quality data work across digital platforms, including data annotation, quality assurance, and AI model training. At Digital Divide Data, I train AI models on large datasets, analyze research feedback to drive improvements, and tune performance to optimize accuracy and efficiency.

I’ve also built strong consistency and speed through freelance online work (including Outlier), completing labeling, categorization, and quality evaluation tasks while meeting tight deadlines. Alongside my AI-focused work, I bring rigorous finance discipline from my Finance Intern role, supported by ongoing CPA training—so I prioritize data integrity, reliability, and self-management in every project.
