About Me

I focus on engineering simulation, software development, and personal server setup, and I enjoy transforming ideas sparked during my learning process into practical projects that are runnable, presentable, and maintainable. My current primary areas of practice include battery simulation, Android development, system deployment, Cloudflare service configuration, and the creation of automation workflows. This website serves as a repository for my projects, technical notes, and access points to my personal web services

Projects

01

Battery Electrode Simulation

Focused on the structural evolution of all-solid-state battery electrodes during the compaction and sintering processes. Conducted modeling and analysis combining FEM, DEM, and SPH methods to study particle contact, pore variation, and material deformation patterns.

Mean - System Privilege & App Management

Developed an advanced system utility application that combines Shizuku-style privilege elevation with comprehensive application management features. Interacts with low-level Android APIs to manage package states, control background processes, and provide users with fine-grained control over their device's application ecosystem.

Films - Automated Web Scraping Tool

Engineered an automated Android utility to scrape and aggregate nationwide cinema coupon data. Implemented a hidden WebView with JavaScript injection to simulate real user behavior and bypass anti-scraping mechanisms. Utilized a state machine for reliable, cross-city data extraction and integrated Apache POI to export the compiled datasets directly into Excel (.xlsx) files.
