Hi, I'm Markzz

I build lightweight, dependency-free software for Termux, Android, and the terminal.
If it needs a 400 MB runtime, it probably doesn't need to exist.

up 2 years — building NoNameOS, Grub Blasters, and whatever scratches the itch.

• 🔭 Building — expanding NoNameOS, a single-file C++17 OS simulation
• 🌱 Exploring — low-level Android internals, TUI design, and game loops
• 🧠 Belief — the best dependency is the one you never installed
• 😗 Fun fact — I rooted a TV stick and reclaimed 1.9 GB of storage

Worms-style turn-based artillery in a single dependency-free HTML file. 2–4 teams blast each other across procedurally generated, fully destructible terrain with 21 weapons (bazooka to banana bomb), a fuel-limited jetpack, floating islands, CPU opponents, shifting wind, a rising sea, and hot-seat multiplayer.

No dependencies. No build step. One file, any modern browser, desktop or phone.

Gum-powered interactive package manager for Termux — a friendlier face for pkg/apt without touching the raw commands. 26 menu options, themes, automated backup/restore, package pin/hold, and a doctor mode for diagnostics.

A complete OS simulation in one C++17 file. Interactive shell, virtual filesystem, built-in utilities, and games — zero external dependencies. Single-file architecture, self-contained complexity, and a genuinely fun way to learn systems concepts.

Screenshot from an earlier build — the current version is far more feature-rich.

A modern, visually stunning Snake game for your terminal — Python + Textual. Neon gradients, particle bursts, combo multipliers up to x5, power-ups (Speed, Slow, Ghost), golden apples, five themes, three difficulties, and a persistent local leaderboard, all in pure Unicode blocks.

Cinematic effects — glow, screen shake, floating score popups — with a layout that adapts to your terminal.

A feature-rich, visually rich modern HTML calculator with 14 themes (Tokyo Night, Catppuccin, Gruvbox, Nord, Dracula…), scientific functions, memory registers, a history tape, keyboard shortcuts, and full responsiveness — all in a single dependency-free page.

Fancy interactive C++17 calculator REPL for Termux — standard library only, single binary. Qalculate-flavored engine: postfix percent (%), right-assoc ^ (-2^2=-4), implicit multiplication, user functions with depth-capped recursion, and fuzz-gated so it never crashes. Ghost autosuggest, transient prompt with ⟨ plusa ⟩ ➤ ornament, and truecolor themed banners (greenit, ocean, ember, sakura, mono).
