PRONOUNS: He / Him

💼 - Software Engineer @ Cursor, focusing on product engineering and design engineering. Building predictable, scalable, rigorous, and beautiful software.

🔬 - Check my portfolio (link above) for projects, research, and publications. I love blending research and engineering — it is so good to have both in one project.

🌍 - I constantly work on side projects that are interesting and can have big impact on people other than me. If you have a good idea, feel free to share with me!

🌃 - I extremely enjoy the outdoors especially exploring nature and stargazing. So when tired, I like to drive out to a state park. Nature gives me the power of all-day coding.

• Full-stack Design Engineer (2020 - now), experienced with React, Next.js, Python, SwiftUI, Postgres, Redis, React Native, SSE / Socket, and much more. I care deeply about code quality + velocity + team standardization.

• Product & Design Engineer (2022 - now), concentrating on the best blend among UI, UX, and DX. High engineering quality + amazing visualization + extraordinary interactions + simple APIs are the best.

• HCI Researcher (2022 - 2024), focused on exploring HCI projects with NLP + medical fields.

• Software Architect (2021 - now), solved complex real-world problems like LLM-friendly CoT agent runners, scalable AI systems, and end-to-end AI agent solutions.

• Machine Learning Engineer (2022 - 2024), using PyTorch, Numpy, Pandas, Transformers.

• I love to build UI component libraries dedicated to the needs of a company / a set of projects because different use cases have different needs. Full customization with headless components is almost the best solution in UI library!

• Growing and holding high bar with team. I love composing big projects into pluggable sub-projects, and re-uniting them like creating a beautiful artwork.

• Programming Languages: TypeScript, Python, Swift, SQL. Previously used C, Java, C#, Go.

• Front-end Tech: Next.js, React, SwiftUI (iOS/iPadOS/macOS), HTML + CSS, and more.

• Back-end Tech: TypeScript API architectures (I love end-to-end type safety), FastAPI, Flask, or any framework that is already working.

• Database: PostgreSQL, MySQL, MongoDB, and serverless options (Neon, PlanetScale).

• Others: CI/CD, Docker, UI/UX Design, native adaptation, 3D model integration, Git, Figma.

• Shipping great product experiences at Cursor — combining refined visual design with reliable engineering.

• Continuing to push the boundaries of design engineering: building interfaces that are both beautiful and deeply functional.

• Making side projects when inspiration strikes and shipping them for free. I deeply believe that the power of user community is more important than small profit in short-term.
