👋 Hi, I’m Ellen!

🎓 UCLA Cognitive Science (Computing) + Data Science Engineering & Digital Humanities 💻 Software Engineer | Product + Data @ the intersection of human behavior and technology

I build systems that turn complex data and ideas into usable, real-world tools. My work spans full-stack development, machine learning, and product-focused engineering—often sitting at the intersection of software, data, and human-centered design.

I’ve developed end-to-end ML pipelines, built web applications and Chrome extensions, and created automation tools that transform raw data into structured, decision-ready outputs. I enjoy working across the stack, from designing intuitive user experiences to implementing the underlying systems that power them.

I’m especially interested in building technology that is not just intelligent, but also intuitive, scalable, and grounded in real human contexts—whether that’s improving classroom workflows, supporting accessibility, or enabling better decision-making.

🚀 Currently exploring opportunities in software engineering, product, and data-focused roles 🤝 Always open to collaborating on impactful projects—feel free to reach out!

🛠 Tech Stack:

Languages: Python, JavaScript, TypeScript, C++, Java, R, HTML/CSS
Data & ML: pandas, NumPy, scikit-learn, TensorFlow
Web: React, Node.js, Firebase
Design & Prototyping: Figma, Adobe Illustrator
Tools: Git, GitHub, Jupyter Notebooks, Google Colab, VS Code, AWS
Other: UX Research, Prototyping, A/B Testing, Data Visualization

✨ Fun Fact:

More of a hojicha person than matcha. Coding to lo-fi beats, or going down a rabbit hole on something random in cognitive science. I’m also weirdly good at guessing movie plot twists way too early 🎬
