Linguistic Data Annotator & Transcription Specialist (Freelance)

OtherAudioTranscription
As a freelance data annotator and transcription specialist, I delivered clean, machine-readable datasets through high-accuracy audio transcription of multi-speaker interviews. My work included meticulous speaker diarization and strict adherence to transcription standards. I also managed the conversion of intricate legal documents by translating Marathi to English for NLP model training datasets. • Transcribed and formatted focus group audio data for linguistic processing in NLP applications. • Conducted Marathi-to-English legal translation, preserving semantics and terminology. • Structured raw transcripts for sentiment analysis and qualitative coding. • Ensured professional compliance and linguistic accuracy in all annotated data.

AI Prompt Engineer & Synthetic Data Creator (Freelance)

OtherImagePrompt Response Writing SFT
In this freelance role, I created highly structured prompts in JSON format to enable complex text-to-image generation tasks for generative AI models. I evaluated synthetic AI-generated images for photorealism, parameter compliance, and cultural or geographic specificity. My documentation of prompt structures and iterative feedback enhanced the accuracy and realism of generative outputs. • Designed and tested advanced prompts for text-to-image generative AI tasks. • Evaluated output quality across lighting, environment, and authenticity metrics. • Iteratively refined outputs to reduce hyper-stylization and maximize real-world fidelity. • Documented prompt patterns and behaviors for model optimization.
