Jimmy

Hi, I'm Jimmy.

AI Product Engineer who builds intelligent products across diverse technology stacks.

I've developed applications spanning from RTOS multimedia players and mobile apps to game servers, set-top solutions, and web platforms. Currently, I'm diving deep into AI, WebAssembly, tooling, and system hacking with Rust—pushing the boundaries of what's possible in modern software development.

As a self-starter and Google Developer for the Web Specialist, I actively contribute to open-source projects and engage with the developer community through local meetups and collaborative initiatives
