What I Know
Beyond languages and frameworks, I have hands-on experience with:
Networking & Protocols: Understanding how HTTP/1.1 and HTTP/2 streaming work, including request multiplexing and streaming optimizations.
Data Flow & Processing: Comfortable with readers/writers/transformers, data piping, and building efficient data streams.
Version Control Mastery: Can manipulate and rewrite Git history, resolve complex merges/rebases, and maintain clean commit structures.
Web Design: Able to design and implement UIs both in React.js and raw HTML/CSS/JavaScript (without relying on frameworks).
Bot & Infra Development: Experience creating Discord music bots, Lavalink clients, and even a from-scratch Lavalink alternative (LunaStream).
Systems & Kernel: Custom kernel building, tweaking SELinux policies, and Android device kernel optimization (e.g., Redmi Note 12 Pro 5G).

🧬 ReZygisk

ReZygisk is a fork of Zygisk Next, a standalone implementation of Zygisk, providing Zygisk API support for KernelSU, Magisk (besides built-in), and APatch.
It aims to modernize and re-write the codebase to C (from C++ and Rust), allowing a more efficient and faster implementation of the Zygisk API with a more permissive license.
