About Me

I'm a Computer Science & Engineering student at The Ohio State University (Class of 2028) specializing in Artificial Intelligence with a 3.79 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 designed over 200 calculus problems with custom evaluation rubrics to test and improve large language models. I've built an Academic Performance App combining a Swift/SwiftUI frontend with a Node.js/Express backend, integrating OpenAI's GPT-4o-mini for syllabus parsing, Canvas LMS integration across 50 universities, and a predictive analytics system for grade simulation and GPA projection.

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

This past summer, I worked as a Waferfab Manufacturing Operator at GlobalFoundries, earning 12 tool certifications across three semiconductor manufacturing toolsets and helping reduce average tool qualification downtime by 42.9% through restructured wait-time intervals. Getting hands-on with cleanroom processes and fab equipment sparked a real interest in the semiconductor industry, and it's a field I'd like to keep exploring alongside my software and AI work. I also serve as House Manager and Head Website Chair for my Theta Tau engineering fraternity chapter.

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

Claude Usage

A macOS menu-bar app showing live Claude usage: 5-hour and 7-day limit percentages, current chat context size, and per-project token/cost estimates. Reuses your existing Claude Code login via the macOS Keychain, pulling exact limits from Anthropic's usage endpoint with a local-estimate fallback. Code-signed with a Developer ID certificate and distributed through Apple's notarization pipeline, with in-app auto-updates powered by Sparkle.
