At Cognizant, I’m currently working as an Intern. My background spans AI/ML engineering, computer vision, and scalable AI systems across edge and cloud environments.

At Aerlync labs, Inc., I engineered an end-to-end network intrusion detection pipeline, training a 1D-CNN classifier with PyTorch and converting it to ONNX for low-latency C++ inference. I containerized the system with Docker and deployed it on an on-premise server.

At Cognicx, I contributed to the Banking Chatbot project by developing automated tests, fixing bugs, and improving test coverage and stability. I’m also studying Data Science at Indian Institute of Technology, Madras.

As an AIML Intern, I engineered an end-to-end Network Intrusion Detection pipeline from data ingestion to production deployment. I designed packet-capturing and protocol-parsing workflows, trained an optimized 1D-CNN classifier using PyTorch, and implemented model checkpointing to maximize validation F1-scores. To achieve low-latency execution, I converted the model to ONNX for lightweight C++ inf
