Endgame
I joined Endgame.ai after launch to help restructure the product and bring the web experience closer to mobile.

Lobby, time controls, and live games. Web at mobile parity.

What Was Done
Restructured the live product, brought web to mobile parity, and designed what came next: Puzzle Run, Club, Watch, Coach, Learn, gamification, custom piece sets and avatars.
How
The product was live, so the job was figuring out what needed to change, not starting over. I tightened existing flows, carried the product language across web and mobile, and designed new features along the way.
The Hans vs Magnus spotlight: one trailer slot for new fans, quick to hide, never fighting Play Online.

The community surface on mobile, in both skins.

The gameplay screen, tightened for the phone.

Three lives, one countdown. The run starts here.

Pick a time, set a target, start the run: web, web-mobile, and app.

The run, continued.

The puzzle flow rebuilt for the phone.

Tournament cards, live boards, standings, chat. The event in your pocket.

Team events on Watch. Coverage few platforms attempt.

Chapter checkpoints: Discovered Attacks, taught with a Nimzowitsch quote.

The lesson system, another pass.

Board and lesson side by side.

Checkpoints that read like chapters.

Review with Coach: accuracy by phase, every move classified.

Standings stripped to signal. MP, GP, nothing else.

Match history and lineup in one overlay, on every platform.

XP, streaks, achievements: the profile as a game board.

Avatars, piece sets, and the full reward loop.

CZAR: the geometric set, drawn from scratch in two colorways.

Hopea is named for an Indian wood type. Soft, rounded pieces on modern, playful boards.

One system, two skins. The whole product flips.
