About

With a degree in Computer Science Engineering in artificial intelligence and machine learning . My expertise lies in Machine Learning domains such as NLP, Deep Learning, PyTorch, TensorFlow, as well as ETL, Hadoop, SQL, and Google Cloud,Docker , airflow. I have hands-on experience with ML libraries like Keras, PyTorch, Scikit-Learn, and Django REST framework, along with proficiency in GIT and Django. In my research, I successfully applied Convolution Denoising Autoencoders to Satellite Image Denoising and hold patents in machine learning and for innovative devices. I have also completed internships where I built AI-enabled applications, developed data dashboards, and worked on predicting mergers and acquisitions using RNN and LSTM models with high accuracy. Apart from that I have worked on LLM (SOTA models like) SAM(segment anything model), grounded DINO integrated these models in our company website, integrated services such as Apache superset and airflow to ease up the development time, worked with AIRFLOW making DAG, dashboards. Also in my previous internship i worked on an AI resume screening software where i led a team of 3 people in an ML team and worked on an application that can give a score according to the Job description this is currently deployed in the company website. here I implemented simple OCR-based models, and cosine similarities algorithms and also used pre-trained models and deployed it in salesforce.
