About Jay Kumar

With over 7 years of experience in developing, deploying, and optimizing machine learning models, I have built a strong foundation in supervised and unsupervised learning techniques. I am proficient in Python, R, and Scala, with advanced expertise in data processing, scripting, and automation. My skill set includes working with machine learning frameworks like TensorFlow, Keras, and PyTorch to build scalable and efficient models, and I have hands-on experience with big data technologies such as Hadoop, Spark, and Apache Kafka for managing large-scale datasets. My background in deep learning encompasses projects involving CNNs, RNNs, and transformer models, while my natural language processing (NLP) expertise includes libraries like NLTK, SpaCy, and Hugging Face for tasks such as sentiment analysis and text classification.
