# SysAdmin Crisis > SysAdmin Crisis is a night-shift simulation solved with 29 gamified Unix commands, including real flags, Tab completion and man. The web (PWA) and mobile (Expo) versions share the same game engine; zero data collection is a constraint tied to the build chain. It is playable today at sysadmincrisis.com. - Role: Designer & Developer - Class: Older / Hobby Projects - Status: Ongoing - Started: 2026-09-23 - Technologies: TypeScript, Next.js, React, Expo, React Native, Zustand - Skills: Game Design, Terminal/CLI Simulation, State Management, Offline-First Architecture, Privacy-Focused Design, Cross-Platform Architecture - Website: https://sysadmincrisis.com - Source: https://muhammetsafak.com/portfolio/sysadmincrisis/ - Language: en-US - Author: Muhammet Şafak --- SysAdmin Crisis is a night-shift simulation where I wanted the command line to be more than surface: the syntax is a gamified Unix, and real commands accept their common flags. `top` really reads the server load, `logs` really lists the event history, `block_ip` really cuts off an attack source; there are twenty-nine commands in total, Tab completion works, and `man ` opens a built-in manual. The shift is built from seven event types; the tutorial section introduces two of them — a memory leak and a DDoS — at a slowed-down pace, using the same commands. The tension only lands if the syntax is actually functional rather than cosmetic. The web version (a Next.js-based PWA) and the mobile version (Expo) share the same game engine; on mobile, the terminal screen is drawn with native components rather than a WebView. Part of the development discipline is not left to code review: a dependency audit, lint, type-checking, the test suite and coverage measurement all run automatically in CI on every push. Zero data collection is likewise not a privacy statement but a constraint tied to code — `fetch`/`XMLHttpRequest` usage in the game packages is blocked by lint rules, and analytics or ad clients leaking into dependencies are blocked by a separate dependency-audit script. While the game runs, no network request is made beyond the initial page load and the service worker update; there are no accounts, analytics or ads. SysAdmin Crisis was prepared for release as v1.0.0 and is playable today at sysadmincrisis.com; it receives no new development, only security and compatibility fixes.
