What I'm looking for

I'm open to additional projects and remote work.

At Welo Data (Welocalize / Welo Global), I annotate and review video, image, audio, and metadata using defined labeling rules. I perform self-QA, flag ambiguous cases, and contribute examples and clarifications to guideline improvements.

At Innodata India Pvt Ltd, I worked on video referring expression QA, progressive masking (MILO), and Vision VLM evaluation. I also assessed multimodal conversations and rated TTS and speech-to-speech audio.

For Skill Demand Pulse, I processed and labeled insights from 1M+ unstructured data records and built interactive dashboards to share findings. I hold a B.Tech in Computer Science (Data Science Specialization) from Brainware University, Barasat.
