🚀 The Challenge
Hackathons are always a race against the clock. This time, I set out to build Budget Brain: an AI-powered advertising budget optimizer that uses Monte Carlo simulation and multi-algorithm validation to help businesses allocate ad spend smarter.
The goal?
- Real-time pipeline visualization
- Multi-algorithm optimization (Monte Carlo + Gradient + Bayesian)
- Confidence scoring and validation
- Accessibility-first UI
- Production quality in just 12 hours
Sounds impossible, right?
It would have been — without Kiro.
🤝 Enter Kiro: My AI Technical Project Manager
Kiro became the organizing brain behind Budget Brain. Instead of drowning in feature creep, last-minute architecture decisions, or messy code, Kiro kept me laser-focused with:
- 📋 Specs & Planning: Clear requirements, user stories, and acceptance criteria
- 🏗️ Architecture Blueprints: Interfaces, component structures, and pipeline layouts
- ✅ Task Tracking: 24 implementation tasks with checkboxes (all completed!)
- 🪝 Code Quality Hooks: Automated reviews for performance, accessibility, and maintainability
In other words: I was coding at hackathon speed, but with enterprise-level discipline.
🧩 How I Structured Conversations with Kiro
I started with simple prompts, and Kiro turned them into complete systems:
Me: “I want to create a decision pipeline to enhance system accuracy.”
Kiro: Broke this into multi-algorithm validation, ensemble methods, and confidence scoring.
Me: “How do I combine multiple optimization algorithms reliably?”
Kiro: Generated the AccuracyEnhancementService architecture with parallel algorithm execution and result combination.
Me: “What’s the best way to validate optimization results?”
Kiro: Produced a 12-task plan covering gradient optimization, Bayesian modeling, LLM validation, and benchmark comparison.
👉 What began as vague ideas became concrete TypeScript interfaces, workflows, and production code.
🪝 Kiro Hooks: Automated Code Review Under Pressure
Even while sprinting, Kiro kept quality high with automated hooks:
- Real-Time Code Review: Flagged long functions, duplicate logic, and type safety issues
- Budget Brain–Specific Checks: Verified pipeline stage error handling, algorithm efficiency, and accessibility compliance
- Performance Optimization: Detected unnecessary React re-renders, suggested caching in Monte Carlo + AccuracyEnhancementService
- Quality Gates: Pre-commit scoring, test coverage checks, maintainability reviews
💡 The result: No technical debt — even in a hackathon sprint.
📑 Spec-to-Code: The Secret Weapon
I paired Kiro with a spec-to-code workflow that looked like this:
- Requirements.md → User stories + acceptance criteria
- Design.md → Technical architecture + TypeScript interfaces
- Tasks.md → 12 concrete implementation tasks with checkboxes
Flow:
👉 User Story → Technical Design → Implementation Tasks → Production Code
This meant:
- Zero architecture decisions during coding
- Parallel dev (frontend + backend in sync)
- Tests and accessibility baked in
- No scope creep (24 tasks, nothing more)
🏆 The Outcome
With Kiro’s help, I shipped:
- Real-time pipeline visualization with animated stages
- Multi-algorithm ensemble (Monte Carlo, Gradient, Bayesian)
- Confidence scoring + AI validation
- 600+ automated tests
- Accessible, mobile-optimized UI
All in 12 hours.
Kiro wasn’t just an assistant. It was:
- The planner (clear roadmap, specs, and tasks)
- The architect (interfaces, algorithms, data models)
- The code reviewer (hooks, checks, and optimizations)
🎯 Takeaway
Hackathons usually trade speed for quality. With Kiro, I had both.
- I moved fast — but with a plan.
- I built complex systems — without messy shortcuts.
- I delivered production-quality features — under hackathon pressure.
👉 Bottom line: Kiro acted as my AI project manager, architect, and reviewer all in one. Budget Brain wouldn’t have been possible without it.
🔮 Looking Ahead
Budget Brain is just the start. The spec-to-code structure and Kiro-powered workflow could be applied to:
- SaaS MVPs
- Enterprise-grade feature sprints
- Team collaboration with automated quality gates
Hackathons taught me that AI-assisted engineering discipline is the new superpower.
✍️ Built with ❤️ during [Code with Kiro Hackathon] 2025.
