    paper Prompt Engineering Project: MatchDay! Soccer Management Simulator

    Overview
    Led end-to-end development of MatchDay!, a soccer management simulation, by harnessing advanced prompt-engineering and AI-assisted coding. Orchestrated architecture, schema modeling, real-time match simulation, and frontend UI via iterative, context-aware prompts to accelerate delivery.

    Key Contributions
    • AI-Driven Development: Crafted 200+ prompts for ChatGPT Codex to generate boilerplate code, refactor services, debug TypeScript/Prisma issues, and optimize game logic.
    • Feature Implementation: Scaffolded dynamic team selection, division assignment, contract and auction systems, fixture and cup-bracket generation, matchday simulation (90 min ≈ 1.5 min real-time), halftime substitutions, live WebSocket broadcasting, and multi-save architecture through prompt refinement.
    • Iterative Debugging: Employed prompt-based chain-of-thought queries to resolve 30+ backend and frontend errors (Prisma constraints, schema mismatches, test failures, Docker warnings), ensuring compatibility and specification alignment.

    Tech Stack & Environment

    Backend: Node.js v20, Express.js, TypeScript, Prisma
    Frontend: React (Vite), TypeScript, Tailwind CSS

    Outcome
    To be delivered: a production-ready simulator with:
    • Modular, maintainable codebase guided by prompts
    • 85%+ test coverage across critical services
    • Scalable design supporting 128-team pools and cup tournaments
    • AI-augmented workflows reducing boilerplate by 40% and accelerating feature rollout by 3×

    This project exemplifies the power of prompt engineering to transform AI from a code-generation assistant into a strategic development partner across the full software lifecycle.
