Freelancer Overview

I am a Biochemistry graduate who took an unconventional path from studying molecular structures to mastering the structure of human language. At HubSpot, I wrote copy and email campaigns that had to be precise, persuasive, and perfectly toned. That discipline taught me something most people overlook: words have layers, and getting them right requires patience, context, and critical judgment. At Women in Tech, I led a web design team, which taught me how to own responsibility, communicate clearly under pressure, and deliver without hand-holding. Now I want to bring that same precision to AI. I understand that behind every intelligent model is a human who decided what good language looks like and I want to be that human. I do not just want a role in AI training; I want to help shape the standard of what AI gets right.

Labeling Experience

Data Annotator

Language Data Contributor | AI Training Project | 2024 Took on self-directed annotation work to build practical experience in AI data pipelines. Tasks included labeling text for tone, intent, factual accuracy, and harmful content detection. Developed a sharp instinct for edge cases the ambiguous, context-dependent inputs that challenge even advanced models. Came away with a deeper appreciation for why human judgment remains irreplaceable in AI development. Built a consistent personal rubric for evaluating AI-generated responses across multiple quality dimensions including clarity, helpfulness, coherence, and potential for harm. Applied domain knowledge from a Biochemistry background and professional copywriting experience to assess outputs in both scientific and general language contexts. Engaged with RLHF concepts by ranking and rating model responses based on accuracy, tone appropriateness, and alignment with human values developing the kind of calibrated judgment that makes annotation work genuinely useful to model training teams.
