Lichess Mobile

---

I ship features to the Lichess mobile app (Flutter), the official client for the world’s most popular free chess platform with millions of players. Across 30+ merged pull requests I’ve built native iOS widgets from scratch, shipped puzzle and openings features, hardened app infrastructure, and polished UX across the board.

iOS Widgets

I built three native iOS home screen widgets, designing the architecture from the widget extension through to the Flutter-to-native communication layer:

• Daily Puzzle Widget — displays the daily chess puzzle with interactive tap-to-open and support for all Lichess board themes and piece sets, synced live from the app (#2965, #2984, #2983, #2982)
• Blog Feed Widget — surfaces the latest Lichess blog posts in three layout variants, respecting kid mode visibility (#2834, #2936, #2935)
• Broadcasts Widget — live tournament broadcasts at a glance, with deep-link navigation into the app (#3007)

The Daily Puzzle widget respects whatever board theme and piece set you’ve chosen in the app.

Puzzle Features

• I built a Puzzle Dashboard showing personal strengths and improvement areas (#2651, #2690)
• Added search within puzzle themes so you can find the exact tactic type you want to practice (#2948)
• Fixed puzzle UI issues: text overflow on long puzzle names, theme sync edge cases, iPad layout regressions (#2759, #2983, #2982)

Game & Analysis

• I shipped custom position loading (FEN) for both computer play and over-the-board mode — set up any position and play from there (#2832, #2947)
• Redesigned the variant picker with icons, descriptions, and a logical ordering so you know what you’re picking (#2760, #2780, #2799)
• Added a low-time warning animation to the clock — the visual pulse when you’re down to seconds (#2788)

Openings Explorer

• Share FEN of the current position straight from the openings explorer (#2632)
• PGN export sharing so you can save or send the game notation (#2664)

App Infrastructure

• I built an in-app log viewer with full-text search, 7-day TTL persistence, pagination, and infinite scroll — useful for debugging on real devices (#2808, #2833, #2852, #2802)
• Improved the User Activity Widget with cleaner data presentation (#2618)
• Fixed a kid mode state issue where restrictions weren’t being applied correctly on cold start (#2930)
