I’m excited to share my personal website!

I’m a UIUC Statistics graduate with a Computer Science minor, and I’ve spent my internships at ByteDance and AWS building backend systems, cloud infrastructure, and AI-powered tools.

But job titles and tech stacks only tell part of the story.

On my website, you can explore the problems I’ve worked on and the systems I’ve helped build:
🤖 At ByteDance: An LLM-powered analytics agent that helped 300+ internal users access data through tool-calling workflows.
☁️ At AWS: A router orchestration service that automated provisioning and reduced manual setup for engineers testing networking infrastructure.
⚡ Beyond internships: Projects including a real-time analytics dashboard processing 100K+ daily events, an event-streaming platform, and an Android app for UIUC students.

The work I enjoy most makes someone else’s job easier—whether that means helping them find an answer, removing a repetitive task, or making a system more reliable.

I’m currently looking for new-grad software engineering opportunities, particularly in backend, infrastructure, and AI systems.

Take a look around, and let me know what catches your attention! I’d love to hear your feedback and connect with people working on similar problems.
