Hello! 👋

ProjectsI’m an M.Sc. Mathematics student at IIT Delhi, building ML systems across NLP, computer vision, and retrieval, including fine-tuning small language models. I care about the work behind the metric: strong baselines, data-leak checks, reproducible pipelines, and evaluation that reflects the real task — including the runs that make my systems look worse.
4-bit QLoRA on SmolLM3-3B that turns an informal civic complaint into schema-checked JSON. On a frozen 50-complaint test it is the strongest learned system — schema validity 0.940, missing-info F1 0.670 — while keyword rules still reach domain F1 0.883, and 36.5% of its factual fields mismatch.
Cited statutory QA over India's 2023 criminal codes — 1,059 sections of BNS, BNSS, and BSA. Every cited section is checked against the retrieved text in plain Python, and deleting the LLM faithfulness checker plus its rewrite loop moved RAGAS faithfulness from 0.309 to 0.543 at Recall@5 0.750.
Deep metric-learning verifier for genuine versus forged signatures. A suspicious 0.999 baseline exposed two dataset leaks; after rebuilding the split and pairing, the 17 MB model holds ROC-AUC 0.986 on unseen writers and 0.877 cross-dataset on NFI.
Text-only risk screener for the 13 CCPA dark-pattern categories plus a benign class, over 6,373 deduplicated UI strings. A leakage audit found 64.8% of test rows echoing a training row, so the split is grouped: fine-tuned DistilBERT scores macro-F1 0.883 there, while a 4 MB TF-IDF pipeline generalises better out of domain at 0.752.
Indian tech-salary predictor built as a reproducible ML delivery project. It cleans 110K records and deploys tuned CatBoost with MAE around ₹1.60 LPA, tracked with MLflow, DVC, and Docker.
