Niharika Mallick

At Amazon Web Services (AWS), I supported EC2, S3, Lambda, OpenSearch, and MSK in enterprise cloud environments. I diagnosed infrastructure, networking, and performance issues using AWS best practices.

For my M.Tech thesis, I designed and implemented multilingual sentiment analysis models using BERT and mBERT. I analyzed AI-related opinions in multilingual Amazon review datasets and improved contextual sentiment prediction with transformer-based architectures.

At GGS Indraprastha University, I worked on Machine Learning and Computer Vision research projects. I developed a CNN-based sentiment analysis model for tweet classification and improved its classification accuracy through feature optimization and model tuning.

I also built a CNN-based tweet sentiment classification system that achieved 92% classification accuracy through optimized text feature extraction. I hold an M.Tech in Computer Science and Engineering from Indian Institute of Technology (ISM), Dhanbad.
