About Me

I'm a Computer Science & Engineering student at The Ohio State University (Class of 2028) specializing in Artificial Intelligence with a 3.791 GPA. I'm passionate about building AI-powered applications that solve real problems, from designing evaluation systems that expose weaknesses in large language models to developing full-stack iOS apps that help students optimize their academic performance.

My experience spans full-stack development, machine learning, and AI integration. As an AI Trainer at Outlier AI, I've created over 200 calculus problems with custom evaluation rubrics to test and improve large language models. I'm currently building an Academic Performance App that combines Swift/SwiftUI frontend with Node.js backend, integrating OpenAI's GPT-4o-mini for intelligent syllabus parsing and predictive grade analytics.

I'm experienced in Swift, Python, JavaScript, Java, and modern frameworks like SwiftUI, Node.js, and Express.js. I work with APIs including OpenAI, Canvas LMS, and REST architectures, deploy to cloud platforms like AWS and Render, and have hands-on experience with prompt engineering and natural language processing.

Currently seeking software engineering and AI/ML internship opportunities where I can contribute to innovative solutions and continue building impactful technology.
