Hi, I am
Computer Science student at Northwestern University
Hi, I'm Liheng, a Computer Science major at Northwestern University graduating in December 2026.
I'm passionate about building software that solves real-world problems. From building inventory system for mental health nonprofit to engineering core payment infrastructure for ticket sales startup, I've consistently focused on delivering greater performance and greater user experiences.
I'm especially interested in full-stack development and systems programming. I'm always looking for opportunities to learn, collaborate, and apply my skills to create meaningful impact.

I collaborated with a team of five other interns to develop an inventory management system for Institute for Therapy through the Arts, replacing their manual, Excel-based inventory tracking process with a digital solution tailored for 100+ therapists. By implementing secure, role-based access and automating workflows like ordering and approvals, we enhanced data accuracy and empowered staff with better visibility and control.

At PATH, my primary responsibility was to enhance the application's frontend UI and integrated the AI model developed by our AI team into the user experience by wrapping it in a middleware API.
