Freelancer Overview

Over the past year, I have worked across multiple AI training data platforms in roles that required both linguistic judgment and technical understanding. At RWS, my work focused on reviewing Indonesian-language AI outputs across text, audio, image, and video formats, evaluating each for accuracy, cultural appropriateness, and safety. At Outlier, I contributed to a code review evaluation project that involved writing prompts and rubrics to assess a model's ability to identify issues in pull requests, propose meaningful fixes, and generate coherent final patches. My background as a practicing software developer gives me a practical foundation that is difficult to replicate through labeling experience alone. Having built full-stack applications, CLI tools, and backend systems, I can evaluate code-related AI outputs against real engineering standards rather than surface-level correctness.

Labeling Experience

Code Reviewer at Outlier

TextComputer Programming Coding
Evaluated a model's ability to perform code review on pull requests. The task involved writing prompts that simulate real PR scenarios, then building rubrics to score whether the model correctly identified issues, proposed fixes that actually made sense, and could generate a clean final patch. The focus was not just on whether the model found bugs, but whether its feedback would be useful to a real developer reading it.

I labeled and compared data sets to improve the accuracy of Indonesian AI language models. My tasks included reviewing AI-generated text, audio, images, and videos to ensure high-quality outputs and safe, culturally appropriate AI responses. I also collected and checked data for reliability and relevance. • Reviewed and rated AI-generated text for fluency and correctness • Evaluated images, audio, and video outputs for contextual accuracy • Compared data sets to refine language model performance • Ensured safety and cultural alignment of AI outputs
