Sai Harshitha Laggu

I am a Master's graduate in Computer Science with hands-on experience developing AI, deep learning, and security-driven applications. I translate research into practical solutions across AI, cybersecurity, and data-intensive domains.

My projects include fraud detection using Graph Neural Networks, hate speech detection with transformers (BERT, RoBERTa), and dynamic resource allocation in 5G networks using Deep Reinforcement Learning. I designed custom RL environments and trained PPO agents to improve bandwidth, latency, and packet loss.

I built a secure audio communication tool using AES-256 with a Tkinter GUI, preserving audio quality, and implemented scalable NLP pipelines on AWS for processing 160K+ comments with a Streamlit dashboard for visualization. I use Python, PyTorch, DGL, Stable-Baselines3, and AWS in production-like workflows.

I am collaborative, research-driven, and eager to apply my technical expertise to real-world challenges that require robust ML models, secure systems, and scalable deployment.
