Prompt Response Writing SFT

As a Prompt Engineer and Data Annotator Contractor at Meta.com, I designed, refined, and tested prompts for agentic AI systems. I performed programming-focused data annotation tasks to support the creation of quality training and evaluation datasets. I evaluated model outputs and iteratively improved prompt design and dialogue quality. • Labeled and corrected outputs in Python, Hack, CPP, JavaScript, SQL, and other programming languages. • Annotated social media and truthfulness-assessment tasks to ensure data accuracy and compliance. • Managed CSV import/export workflows for annotation processes using Python and Fast API playgrounds. • Conducted rigorous qualitative analysis and debugging to validate and enhance model responses.
