Measured runtime and rendering behavior
No network calls or async logic.
Trust boundaries and protection model
What improved engineering quality over time
Resulting system quality and product impact
Delivered a fully playable browser game with:
Building a serious product with high engineering standards? Let's architect it with clarity.

Slide 1 of 4
Hangman-style browser game with deterministic state transitions and synchronized visual feedback.
Custom hook encapsulating complete game rules and transitions
Input lock and duplicate-guess guards for deterministic gameplay
Life overlay synchronization with terminal-state logic
Constraints and product-level risks
Implement a word guessing game that:
Implementation direction and execution strategy
Assembly Endgame is a Hangman-style browser game built with React and TypeScript.
Game rules are isolated inside a custom hook, ensuring deterministic state transitions and synchronized visual feedback.
System boundaries and layered decisions
Layer-based separation:
hooks/ -> useGameLogic components/ -> UI blocks data/ -> static datasets types/ -> GameState definitions
Game logic fully encapsulated in the custom hook.
Next.js App Router
Structured Data Layer
Domain Boundaries
Runtime Discipline
Trust Boundaries
Client-side UI with component-driven game board and keyboard
