🎓 Hi, my name is Zairui (Katherine) Yang, and I’m a passionate software engineer specializing in backend systems, data engineering, and full-stack development. I’m currently pursuing my MSc in Computer and Information Technology at the University of Pennsylvania, graduating in May 2025.
- Tesla (Factory Software Team) → Migrated a legacy .NET ETL system to Golang & React, optimizing scalability for 200+ factory processes and improving system efficiency.
- SciFeCap (Quant Trading) → Built a WebSocket-based real-time data pipeline, reducing database load by 40% and enhancing financial signal processing.
- MCIT Slack Bot → Developed an AI-powered alumni search tool integrating OpenAI API, Redis, and Celery, scaling to 300+ users.

I have hands-on experience with Golang, Python, Java, C++, JavaScript, and SQL, and I work extensively with React.js, Next.js, Node.js, PostgreSQL, MongoDB, Kafka, Docker, and AWS. My passion lies in building scalable, high-performance systems and tackling complex engineering challenges.
I love A Cappella 🎤, photography 📷, traveling & the outdoors ⛰️, surfing 🏄♀️, and spending time with cats 🐈.
