Leave management for IIT Mandi faculty, built from the institute's own PRD.
Balances are never stored. They are derived on every read from an append-only ledger and database triggers refuse any edit to the ledger or the audit log. Real service rules included: leave across 31 December, conversion caps, no self-approval.

Ticketing and gate control for the fest's biggest night.
Every ticket can be claimed exactly once through an atomic database update, so two gatekeepers scanning the same code can never both let it in. 13 commits shipped live on event day without downtime.

Finding objects that are designed not to be found.
Adapted PAIS to camouflaged objects with 10% labels, designed a DINOv2 + LoRA decoder with SigLIP-2 text-guided queries and reproduced UCOD-DPL with two-pass SAM2 refinement and test-time soft voting.

05 · Team of 4 · Jan - May 2026
Teaching a vision model to forget one domain and keep the rest.
With N domains to keep and one to forget, the forget signal gets outvoted N to 1. We rebalanced the loss, then adapted SCRUB from forgetting single samples to forgetting whole domains.
