At Visual Data Computing Group (VisDom), IISER Bhopal, I proposed a query-aware token selection method for late-interaction visual document retrieval. My first-author paper on the work was accepted at the IEEE International Conference on Data Mining (ICDM 2026).

At SpectraX Management LLC, I built a document classifier that reached 0.91 precision and developed OCR preprocessing that reduced bulk processing time by 75.4%. I also built Inbox Radar, a web app that monitors Gmail inboxes and flags unanswered conversations, deadlines, unpaid invoices, and renewals.
