What I'm looking for

I'm looking for detail-sensitive work where I can improve data quality, support AI or legal-document workflows, handle sensitive information responsibly, and contribute to measurable process improvements.

I annotate large datasets at DataAnnotation to improve machine-learning training accuracy, correct dataset errors, and test AI models through response-improvement scenarios.

At The Mendoza Law Firm, I draft, edit, and review documents supporting humanitarian visa applications to USCIS, including VAWA, U-Visa, and T-Visa cases. I handle forms such as I-360 and I-914, along with affidavits, RFEs, identity documents, translations, and supporting evidence.

I led an internal workflow optimization project across different areas of the firm, directing a dozen people and improving internal quality control by up to 30% and output by 15% in specific areas. I've also been recognized repeatedly as a Top Performer.

With a B.A. in English Language and Literature focused on African and Caribbean postcolonial literatures, I bring native Spanish, fluent English, and additional French, Swahili, and German language capabilities to detail-sensitive work.
