Hi there, I am H2Sxxa! 👋
I am a full-stack developer and technology enthusiast.
Major in Artificial Intelligence, but I am more interested in making applications.

My Programming Journey
I first got access to a computer when I was a little kid, and Scratch was my introduction to programming.
At the end of 2020, I started learning programming with Python and Java because I wanted to make Minecraft mods. Back then, I didn’t even understand what OOP was. Writing Java code and getting a Gradle project to run felt incredibly difficult.
Eventually, I gave up on Java for a while and started writing some terrible Python scripts to scrape things from the internet. Those small experiments helped me understand what programming was really about.
In 2021, I still wanted to make Minecraft mods, so I started using MCreator. To be honest, I don’t think it’s a very good tool. I spent more than half a year building questionable mods and unfinished projects before finally abandoning it and returning to Python.
By late 2021 and throughout 2022, I started using NoneBot and deployed a zhenxun_bot instance. Influenced by the NoneBot ecosystem, I also used NonePrompt to build a tool that helped MCreator users set up their mod development environments, especially the infamous gradlew setupDecompWorkspace process.
(NoneBot’s codebase is excellent. Its design and coding style still influence how I write Python today.)

During late 2022 and 2023, I started building my own bot from scratch and created my first Minecraft mod, Kekkai.

You can also find my Minecraft mods on Modrinth.
In the second half of 2023, I began learning Flutter and Rust.
Flutter was amazing. The idea that you could build a polished application in just a few hours completely changed my perspective on app development. With Flutter, I refactored MCreator_Setup and explored some unconventional approaches to solving mod development environment issues, including JAR class patching.

In late 2023 and throughout 2024, I founded CCZU-OSSA. Honestly, I just wanted to find some like-minded people. Looking back, I’d say it was a success.
2024 became a major milestone in my programming journey. I learned how Python actually works under the hood and discovered some crazy ways to patch and extend it. I learned how to combine Rust and Flutter using rinf, built several interesting applications, met many amazing people, and made some great friends along the way.
I’m truly grateful for everything I experienced during 2024.

From late 2024 to the first half of 2025, I joined Reflex AI Limited and worked with the team on Sekai App, an AI companion application built with Flutter.

From August 2025 to April 2026, I worked at Kazama Inc. as a Next.js developer and helped build kusart.com (formerly kusa.pics).
During this period, I learned how to use AI-assisted development effectively. More importantly, my front-end development skills gradually matured through real-world product development and collaboration.
After leaving Kazama, I returned to working on open-source projects.

I’m still learning, building, and exploring new technologies every day. The world of software development continues to evolve rapidly, and I’m excited to see where it goes next.
