👋 Hi there, I'm Feng Kaiyu.

I am an individual who enjoys experimenting, thinking, learning, and creating.

I work on analytical database infrastructure, with a focus on storage and metadata systems.

My background spans blockchain research, full-stack development, and distributed systems. I am particularly interested in building infrastructure for data-intensive systems and resource scheduling.

I'm also a lover of LaTeX, Neovim and Linux.

• 🔭 Focused on systems, infrastructure, and databases.
• 🌱 Currently learning more about storage engines, metadata systems, and resource scheduling.
• 🤝 Open to collaborate on infra, databases, and developer tools.
• 🥅 2026 Goal: Rebuild a healthy body, lifestyle, and learning routine.

🔧 Technical Stack (Still Expanding)

In the past, I worked on blockchain research, full-stack development, and distributed systems; today, I focus on analytical database infrastructure, especially storage and metadata; looking ahead, I want to keep building infrastructure for data-intensive systems and resource scheduling.

As a first-year graduate student, I spent times in blockchain consensus algorithms and LaTeX package development:

During junior and senior years, I did full stack development and did some works in Web3, Architecture, and Compilers.

As a sophomore, I wrote feverrpc and started to use Arch Linux:

During my freshman year, I divided my time between participating in ACM and CTF competitions, while working on other small projects:

One of my earlier research projects was Jasmine, a blockchain consensus algorithm prototype.
