Zero-Day: A Zero-Day Attack Detection & Mitigation Framework for Kubernetes
A six-layer framework that models Kubernetes container behaviour as a temporal graph, scores it with a TGNN + 3-model ensemble, explains every alert with XAI, and safely auto-contains threats through a Kubernetes operator.
Multi-Modal Prompt Injection Defense Gateway (MPI-DG)
An inline zero-trust security proxy for LLMs and multimodal models: structured-query isolation (IFS-R), multi-turn temporal risk scoring (SWCSA), and frequency-domain image/audio sanitization — with no model retraining.
Hybrid P2P-Cloud Anonymous Transfer Engine
A privacy-first file-transfer platform that races WebRTC peer-to-peer against an AWS S3 relay on a 5-second timer, buffers chunks in IndexedDB to keep RAM flat, and self-destructs cloud copies with a Lambda nuke plus a 24h lifecycle.
Plant Disease Detection & Hybrid Treatment System
A field-resilient crop-diagnosis platform: a dual ResNet-50 ensemble with synthetic channel augmentation and 10-pass test-time augmentation (96.9% test accuracy over 38 classes), plus a GPT + offline-database treatment advisor.
FloatChat — Conversational Oceanographic Intelligence
A dual-engine RAG system that turns 10 years of ARGO float NetCDF data into natural-language queries — LangChain + GPT SQL agent online, a local sentence-transformer + spatial-regex engine offline, over 255k depth profiles in PostGIS.
Building a Production RAG Pipeline That Doesn't Hallucinate
How I took a naive retrieval-augmented setup from 61% to 92% answer faithfulness — chunking, hybrid retrieval, a reranker, and grounded generation with citations.
