About Me

I am a final-year B.Tech CSE student and a hands-on engineer building end-to-end systems that combine machine learning, backend engineering, and Android applications. I enjoy taking research ideas and turning them into production-ready solutions.

I’ve built projects across NLP (NER with BERT, RAG systems), Computer Vision (pothole detection), and Android apps (Kaksha Connect, Alarm app). I also build secure backend services using Java and JWT for authentication.

Selected Projects

A few projects that showcase my work across NLP, CV, backend, and mobile development.

NER using BERT

Named Entity Recognition system built using a fine-tuned BERT model. High-quality dataset preprocessing, tokenization, and evaluation with F1 metrics.

NLPBERTPyTorch

RAG — Retrieval Augmented Generation

End-to-end RAG pipeline: document ingestion, chunking, vector embeddings, FAISS retrieval, and generator integration for contextual Q&A.

Pothole Detection

Computer Vision model to detect and localize road potholes using a custom dataset and YOLO-style detection model. Includes a simple Android demo for field testing.

CVObject DetectionAndroid

Java JWT Authentication

Secure authentication service using Java (Spring Boot) with JWT-based stateless auth, refresh tokens, and role-based access control.
