Voice-controlled chess with an AI opponent — accessible play that keeps strategy and learning at the center, built on Flutter with a Node.js rules engine on PostgreSQL and AWS.
Selected screens across the product — from marketing surfaces to in-app flows.
Challenge
Small-screen touch chess punished imprecision; many curious players never got past tiny pieces, abstract coordinates, and noisy environments.
Solution
Designed a voice-first move loop with confirmation and disambiguation so players could say the square, say the move, or ask the coach aloud.
Challenge
Speech intent had to stay aligned with a deterministic rules engine so illegal moves, threats, and undo safety rails never diverged from the board state.
Solution
Paired low-latency speech parsing with a shared rules-engine contract and structured clarification UI when utterances were ambiguous.
Challenge
Beginners needed explainable hints and blunder alerts without overwhelming hobbyists who wanted a stiffer opponent.
Solution
Shipped adjustable AI difficulty with coach mode that reads legal moves, threats, and simple plans aloud alongside optional blunder alerts.
Challenge
Players with motor or vision differences needed larger pieces, high contrast, haptics, and pacing presets without a separate app experience.
Solution
Added accessibility presets and COPPA-aware under-13 defaults so inclusive UX patterns were available from first launch, not bolted on later.
