As an experienced Software Engineer with a strong background in full stack development and AI and expertise in Java, C#, and SQL/no-SQL technologies, I believe I am well-suited for a variety of development tasks and roles. At Outlier AI, I excel as a Software Developer, focusing on creating advanced AI solutions and optimizing data processing. I engineered an interactive chatbot using React, Node.js, and Express, which boosted user engagement through enhanced natural language processing and real-time responses. I improved data preprocessing efficiency by 30% and developed high-performance machine learning models with Java, Python, and TensorFlow. My efforts in integrating cutting-edge algorithms increased forecast accuracy by 20% and enhanced model performance by 25%. I collaborate closely with cross-functional teams, conducting rigorous experimentation and model evaluation while maintaining comprehensive documentation to ensure robust AI solutions. Having worked as a Full Stack Developer at Verizon, I have gained valuable experience in developing and enhancing websites using ASP.NET Core and Angular. I have also successfully integrated Azure and Akka for efficient user node distributions, as well as implemented RabbitMQ and Kafka for effective user information queuing. Additionally, I have designed and developed REST APIs for user management, optimizing for scalability and reliability. During my tenure as a Software Engineering Consultant at Tata Consultancy Services, I led the development of a banking management system using Java and Oracle (MySQL), applying agile methodologies. I also developed a news web application with MEAN Stack, focusing on both frontend and backend, and managed MongoDB for user data storage. Working in agile teams, I contributed to the successful implementation of project development phases. With a Bachelor's degree in Computer Science from the University of Illinois, Chicago, and a GPA of 3.5, I have a strong foundation in computer science principles and a passion for solving comple
