3 IEEE Systems.Edge-to-Cloud.

I build inference systems for resource-constrained environments — ML pipelines that run at the edge, IoT sensor networks that operate offline, and full-stack products that ship to real users.

My work spans three domains: AI/ML (EmotiScan, Agri-Guard — 2 IEEE papers), IoT & embedded systems (AgroFog+, Emergency Ventilator — 1 IEEE paper), and full-stack engineering (LifeLineX, this portfolio).

LifeLineX

<100ms WebSocket P95 latency · 3 dashboard roles

Emergency patients lose critical minutes because hospital ICU availability is invisible to paramedics. Every second of delay compounds mortality risk.

Real-time emergency response network with <100ms WebSocket latency. Architecture: React frontend → Node.js/Express API → Socket.io broadcast → MongoDB for audit log. Three dashboards: patient SOS, hospital admin (live bed count), paramedic dispatch. Twilio SMS fallback for no-data coverage. Chose Socket.io over REST polling to eliminate 1-2s round-trip delay in emergency context.

Agri-Guard

94.8% acc · 28ms CPU inference · 38 classes · PlantVillage · baseline: 63%

Indian farmers lose 15–25% of crops to disease annually. Manual diagnosis requires an agronomist visit — days of delay at high cost, inaccessible to 85% of small-scale farmers.

Dual-system platform: (1) MobileNetV2 CNN fine-tuned on PlantVillage dataset — 94.8% accuracy across 38 disease classes, 28ms inference on CPU. Chose MobileNetV2 over ResNet50 for 3× faster inference on edge hardware. (2) ESP32 + DHT11 IoT node publishing temperature/humidity every 30s via MQTT to a React dashboard. Flask API serves inference endpoint. Baseline: Haar+SVM at 63%.

EmotiScan

93.2% macro-F1 · 22ms CPU · FER2013 (7 classes) · edge-only inference

Commercial emotion APIs cost per-request, send data to cloud, and require network connectivity — incompatible with therapy rooms, offline education tools, and privacy-sensitive HCI applications.

Edge-deployable facial emotion recognition system. Pipeline: OpenCV Haar Cascade face detection → 48×48 grayscale ROI → MobileNetV2 (FER2013, class-weighted for 1.5% Disgust imbalance) → 7-class softmax → 5-frame temporal smoothing buffer. 22ms inference on CPU — 4× faster than ResNet50. Zero API dependency. Initial overfit at epoch 12 (val=73%) → Dropout(0.5) + L2 → val=88%.

LifeLineX — Real-Time Emergency Response

WebSocket latency <100ms · 3 dashboards (patient / hospital / paramedic)

Emergency patients lose critical minutes because the nearest hospital may have no ICU capacity. LifeLineX connects patients, paramedics, and hospitals on a single WebSocket network — hospital availability is visible before ambulance arrival. Built with React, Node.js, Socket.io, MongoDB, and Twilio for SMS fallback.

Agri-Guard — CNN + IoT Crop Intelligence

94.8% accuracy · 38 disease classes · PlantVillage dataset · ESP32 sensor node

15–25% of Indian crops are lost to disease annually because diagnosis is slow and expensive. Agri-Guard gives any smartphone user a 94.8% accurate crop disease diagnosis (MobileNetV2, PlantVillage dataset, 38 classes) and an ESP32+DHT11 IoT node for real-time field monitoring. Baseline comparison: Haar+SVM at 63%.
