About Me

Who I am.

A brief look at my background and what I'm passionate about.

I’m a Google Summer of Code 2026 Contributor with the Apache Software Foundation, where I'm helping build high-performance, real-time data infrastructure.

My journey into open source began with small documentation fixes and grew into authoring FIP-37 for Apache Fluss, a proposal to integrate native bitmap analytics into the storage engine. I'm now leading its implementation for my GSoC project.

I thrive on the challenges of building reliable, scalable, and efficient backend systems. I'm always open to discussing distributed systems, open-source strategy, or connecting with fellow developers.
