hello, my name is
Tiffany Yung
I enjoy building end-to-end products powered by data and machine learning, with experience across full-stack and backend systems.
Alongside coursework in systems programming, design & analysis of algorithms, information systems, and computer graphics, I’m constantly building projects that challenge and excite me!
Explore my workAbout Me
I'm currently a CS & Math double major @ Purdue University with a minor in Mathematical Econ.
Last summer, I worked as an SDE intern at AWS, building features for the internal ticketing API used across Amazon. I’m looking forward to returning this summer to dive deeper into large-scale systems and backend infrastructure. Currently, I’m balancing coursework with projects that let me experiment with new ideas and technologies.
Outside of coding, you can usually find me dancing, playing poker, taking photos on my Sony a6700, or searching for good matcha!
Here are a few technologies I've been working with recently:
- >C/C++
- >Pinecone
- >SQL
- >LangChain
- >Python
- >Flask
- >Tailwind

Experiences
Software Development Engineer Intern @ Amazon Web Services
May 2025 — August 2025
- Engineered Amazon's internal ticketing API handling 130M+ daily requests to support priority and label-based filtering and sorting, improving issue management and triage for 1M+ employees.
- Implemented end-to-end changes across API model, service logic, and datastore layers, maintaining consistency across CRUD operations and preserving backward compatibility.
- Designed unit and integration tests to validate request/response behavior, ensuring safe production rollout.
Things I've Built
