Hi, I'm Arunaprabha K N
Engineer · Researcher · Hackathon Winner
I build systems at the intersection of human experience and machine intelligence — from emotion-aware voice diaries to satellite imagery deep learning. IEEE published. GATE qualified. Google Gemini Ambassador.
Medical data is scattered and unstructured. LLMs hallucinate on medical facts without reliable grounding.
A RAG pipeline grounding LLM responses in verified medical documents — fast, accurate, hallucination-resistant.
1st place + ₹5,000 at SNS 8-hour hackathon. Iterated from a prototype built at Hack-A-Cure, VIT Chennai.
Journaling apps send data to the cloud. No existing voice tool runs offline and understands emotional context.
Offline-first Kotlin app that transcribes speech locally, detects emotional tone, and reflects it through the journaling experience.
IEEE ICECA 2025 published. Fully on-device NLP — zero data leaves the phone at any point.
Single-image SR loses spatial detail recoverable from paired satellite shots. Supervision data is rarely available at runtime.
Dual-image fusion deep learning model with attention architecture in PyTorch. No ground truth needed at runtime. Streamlit demo.
Handles real-world satellite pairs without paired supervision. Built end-to-end for Bharatiya Antariksh Hackathon.
Classifiers that retrain on every run are too slow for deployment. Preprocessing overhead adds unnecessary latency.
TF-IDF pipeline with optimized preprocessing that persists the trained model — inference runs without retraining.
Fast, production-ready inference designed with real deployment constraints in mind from the start.
Needed a real full-stack system covering seat selection, user accounts, and booking history.
Full-stack platform with user dashboard, booking flow, and history tracking. Frontend to backend on XAMPP.
Working system demonstrating full-stack capability across frontend, backend logic, and relational DB design.
No-code tools are desktop-only and complex. Building a site from a phone is still inaccessible for most people.
Flutter mobile app for drag-and-drop website creation with accessibility-first UI/UX design throughout.
Actively in development. Core layout engine and component system in progress.
Single-sensor flood monitors miss hidden risks and produce false alarms in remote deployments.
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.
Robust edge monitoring design for real-time flood awareness. Ideal for remote sites with low-connectivity GSM reporting and low-power deployment.
Traditional soil sensors leave hardware waste in fields. Retrieval at scale is costly and impractical for farmers.
Biodegradable sensor patches embedded into soil — monitor conditions in real-time, then decompose naturally. Zero retrieval, zero hardware waste.
Enables dense IoT deployment at agricultural scale without the environmental or logistical cost of hardware recovery.
"AI-Powered, Privacy-First Emotion-Aware Voice Journaling" — accepted and published at ICECA 2025.
Won first place and ₹5,000 cash prize at the 8-hour AI/ML Hackathon at SNS College of Technology with MedRAG.
Cleared the Graduate Aptitude Test in Engineering as an undergraduate — national-level exam for PG admissions and PSU recruitment.
Sustainable microgrid and energy optimization project. Ranked in the top 10% of over 500 competing teams.
Built dual-image satellite super-resolution model with PyTorch attention-based architecture.
Secured second place at the Anna University Zonal Chess Tournament.
Organized and hosted a 30+ hour hackathon as MC — end-to-end participant coordination, judging, and event management.
Recognized for communication and public speaking in Tamil language.
Promoting AI literacy, organizing workshops, and representing Google's AI ecosystem on campus.
German: Completed A1.1 at Inlingua · A1.2 exam completed · Progressing toward A2
