I design and build apps, the backends behind them, developer tools and, lately, AI agents. Sometimes the launch film too. This reel is some of it.

Still curious.

Featured build · 2026 · Live, and free to play

Hit. Fly. Repeat.

A stickman brawler where the hit is the whole game.

Every hit is told as loudly as it landed, from a dry tak to a BOOM that stops the fight. It runs in the browser on a fixed 120 Hz simulation, and the server checks every leaderboard run by replaying it. I built the game, its print shader, the sound, the Rust backend and the trailer.

Twistgrip

The pit wall in your pocket.

A companion app for the TVS Apache RTR 310. The bike broadcasts far more over Bluetooth than its dashboard shows, so I read the official app, captured the stream, mapped it one control at a time and wrote my own decoder. The app turns it into a live cockpit, rides you can replay, real fuel costs and a Wear OS watch face. No account, no ads, and nothing leaves the phone.

twistgrip.arunprakashg.com Read how I reverse-engineered it

A personal, non-commercial project. Independent, and not affiliated with TVS Motor Company.

Twistgrip's live cockpit on a phone: 99 km/h in fifth gear, with the rev arc, throttle trace, range and fuel.
Mounted mode, turned sideways: gear, a large speed readout, shift lights and a rev bar.
Mounted mode
The Wear OS ride screen: 48 km/h in third gear with a rev arc round the edge.
On the wrist
  1. 01 · Read the appStatic analysis of the official client gave me the BLE service, the 20-byte frame layout and candidate offsets.
  2. 02 · Ask the bikeThe cluster stays silent until the phone writes one status frame, then it streams about seven frames a second.
  3. 03 · Diff one controlA script reads out each instruction and timestamps it. Flip one switch, diff the bytes, and the field gives itself away.
  4. 04 · Write only what is safeEverything is read-only except the one keep-alive frame. The risky command frames are deliberately left alone.

Open source · Claude Code plugin · MIT

Plan in waves. Build in parallel.

Each phase gets its own subagent and git worktree, on the cheapest model that can do the job.

$ claude plugin marketplace add ArunPrakashG/wave-planning$ claude plugin install wave-planning@arunprakashg-plugins

Example · a notes app, 7 phases

Seven phases. Run one by one, they take seven steps. Grouped into waves, they take three, and each wave is checked before the next one starts. Same work. Less waiting.

Behind the scenes

My other build.

The machine this reel was made on.

I love building PCs. This is the one on my desk: I put it together myself, it runs CachyOS with Hyprland, and it ran the benchmarks in my notes.

    Generative UI Without HTML: Letting the Model Design in a Shader

    I wanted Claude to design anything, not fill in a component catalog. I tried a small language, then free-form HTML in a sandbox, then a single GLSL fragment shader with compile errors and a rendered frame fed back to the model. What each attempt got right, why I dropped it, and what I haven't measured.

    Twistgrip: Reverse-Engineering the RTR 310's Bluetooth Stream

    The RTR 310's cluster broadcasts far more than a speedometer shows. How I studied the official app, taught a capture script to speak its controls out loud, and mapped the bike's Bluetooth stream one field at a time.

    Impact Frame: A Browser Brawler Where the Hit Is the Whole Game

    Impact Frame is a free stickman brawler that runs in your browser. Every hit is told as loudly as it landed, on a fixed 120 Hz simulation the server can replay. How the hit, the print look, the sound, the enemies and the leaderboard were built.

    Wave Planning, Packaged: The Claude Code Plugin

    Wave planning is now a Claude Code plugin. It plans a build into waves, routes each phase to the cheapest adequate model, and runs every wave in parallel git worktrees with a gate before the next one starts.
