Case Studies

RAG · NLP🏆 1st Place · ₹5,000
MedRAG — Medical AI Assistant
SNS College of Technology · 8-hour Hackathon
Problem

Medical data is scattered and unstructured. LLMs hallucinate on medical facts without reliable grounding.

What I Built

A RAG pipeline grounding LLM responses in verified medical documents — fast, accurate, hallucination-resistant.

Result

1st place + ₹5,000 at SNS 8-hour hackathon. Iterated from a prototype built at Hack-A-Cure, VIT Chennai.

Voice-Based Emotion-Aware Diary
Privacy-first, fully offline journaling app
Problem

Journaling apps send data to the cloud. No existing voice tool runs offline and understands emotional context.

What I Built

Offline-first Kotlin app that transcribes speech locally, detects emotional tone, and reflects it through the journaling experience.

Result

IEEE ICECA 2025 published. Fully on-device NLP — zero data leaves the phone at any point.

Dual-Image Satellite Super Resolution
Attention-based fusion for satellite imagery enhancement
Problem

Single-image SR loses spatial detail recoverable from paired satellite shots. Supervision data is rarely available at runtime.

What I Built

Dual-image fusion deep learning model with attention architecture in PyTorch. No ground truth needed at runtime. Streamlit demo.

Result

Handles real-world satellite pairs without paired supervision. Built end-to-end for Bharatiya Antariksh Hackathon.

Spam Email Detection System
Efficient classifier with persistent model optimization
Problem

Classifiers that retrain on every run are too slow for deployment. Preprocessing overhead adds unnecessary latency.

What I Built

TF-IDF pipeline with optimized preprocessing that persists the trained model — inference runs without retraining.

Result

Fast, production-ready inference designed with real deployment constraints in mind from the start.

Movie Ticket Booking System
Complete end-to-end platform
Problem

Needed a real full-stack system covering seat selection, user accounts, and booking history.

What I Built

Full-stack platform with user dashboard, booking flow, and history tracking. Frontend to backend on XAMPP.

Result

Working system demonstrating full-stack capability across frontend, backend logic, and relational DB design.

No-Code Website Builder App
Mobile-first website creation for everyone
Problem

No-code tools are desktop-only and complex. Building a site from a phone is still inaccessible for most people.

What I'm Building

Flutter mobile app for drag-and-drop website creation with accessibility-first UI/UX design throughout.

Status

Actively in development. Core layout engine and component system in progress.

IoT · Edge Intelligence
Smart Floating Flood Monitoring System
Multi-sensor flood risk detection with GSM alerts
Problem

Single-sensor flood monitors miss hidden risks and produce false alarms in remote deployments.

What I Built

TTGO T-Call float combining water pressure, turbidity, and TDS sensor fusion into a Flood Risk Score, plus GSM alerting for warning and danger states.

Result

Robust edge monitoring design for real-time flood awareness. Ideal for remote sites with low-connectivity GSM reporting and low-power deployment.

IoT · Concept
AgroSense 2.0 — Biodegradable Soil Patch
Zero-waste precision agriculture sensor system
Problem

Traditional soil sensors leave hardware waste in fields. Retrieval at scale is costly and impractical for farmers.

The Concept

Biodegradable sensor patches embedded into soil — monitor conditions in real-time, then decompose naturally. Zero retrieval, zero hardware waste.

Why It Matters

Enables dense IoT deployment at agricultural scale without the environmental or logistical cost of hardware recovery.
