🌿 Plant Leaf Disease Identification — Ensemble Learning + Mish Activation
Research internship project at Botho University (Jun 2024–Aug 2025) building a mobile/web app to classify plant leaf diseases using ensemble deep learning models with the Mish activation function. Involved literature review, model development, and co-authoring a Scopus-indexed / IEEE conference paper.
| Stack | Scale | Impact |
|---|---|---|
| Python, TensorFlow, Ensemble Learning, Mish Activation, OpenCV | Full research-to-publication cycle | Published at IEEE ICDSBS 2025 (read the paper) |
🥽 Agriverse — Smart Farming Experience with Digital Twinning
Built during the Metaverse Internship at Munjal BCU Centre of Innovation & Entrepreneurship (Feb–May 2025). An immersive VR smart-farming simulation featuring teleportation systems, an agriculture museum, and a live digital twin synced with real-world sensors (ESP32/ESP8266, DHT11, LDR) for temperature, humidity, and light data via Firebase.
| Stack | Scale | Impact |
|---|---|---|
| Unity3D, Blender, C#, Firebase, ESP32/ESP8266, Arduino | Full VR environment + real-time IoT digital twin sync | Delivered as core internship output; hands-on XR + IoT integration |
📦 AI-Assisted Cartonization & Packing Optimization System
An intelligent cartonization system for e-commerce logistics, tackling the NP-hard 3D Bin Packing problem via First Fit Decreasing, Best Fit, and 3D Bin Packing heuristics, enhanced with TensorFlow-based pattern analysis. Secured with Spring Security and role-based access, with an Angular frontend for real-time 3D visualization of packing.
| Stack | Scale | Impact |
|---|---|---|
| Java, Spring Boot, Spring Security, Angular, Python, TensorFlow | Heuristic + ML-assisted optimization engine | Near-optimal real-time packing suitable for warehouse/logistics use |
