From Idea to MVP in a Week

Case Study: My First AI Experiment


Background

For years, my coworkers and I have bonded over fantasy football through the Sleeper app. Beyond the friendly competition, I always appreciated Sleeper’s intuitive interface and the little UX details that made managing my team a joy.

When I discovered they offered a public API, my mind immediately began racing. As both a sports enthusiast and a data junkie, I saw an opportunity to merge two passions—sports and analytics—into a personal project.

But like many developers with side-project dreams, I never “found the time.”


The Shift in Mindset

Recently, while exploring new career opportunities, I realized I wanted to lean more into product ownership. After 15+ years as a developer—with Agile and Scrum sprinkled in over the last decade—it felt like the right time to transition into a more strategic, product-focused role.

Around that same time, I had a conversation with a coworker about the power of AI in accelerating software development. I decided to put that theory to the test—treating this as both a passion project and a live case study in product creation with AI.


The Idea

I wanted to create an Awake Fantasy Draft Analyzer App—a tool that not only consumed Sleeper’s public API but also:

  • Analyzed live and historical fantasy league data
  • Produced customized insights based on draft strategy, league format, and player availability
  • Adapted analytics dynamically to changing circumstances (injuries, trades, waiver wire movements)

In short, I wanted an app that could do more than show me data—it needed to interpret it like a seasoned fantasy GM.


The Process

Instead of coding from scratch, I decided to flex my product owner muscles. My role was to:

  1. Define end-to-end product specifications—clear, detailed requirements, architecture diagrams, and data flow.
  2. Leverage Claude Code as my AI development partner to turn those specifications into working code.
  3. Iterate rapidly with AI as the “developer” while I played the role of “PO + Architect.”

I designed the app’s logic to:

  • Pull data from Sleeper’s endpoints
  • Normalize and enrich the datasets for more meaningful comparisons
  • Generate complex, scenario-based insights

Execution Timeline

Day 1–2:

  • Drafted detailed specifications, use cases, and data models.
  • Fed Claude precise prompts to build API integrations and core analytics functions.
  • Got a working baseline app within 48 hours—basic but functional.

Day 3–5:

  • Added personal touches and fine-tuned logic.
  • Customized UI elements for faster decision-making.
  • Tested against real league data for accuracy.

Day 6–7:

  • Fixed edge-case bugs (bye weeks, unexpected injuries).
  • Optimized performance and finalized the V1 MVP.

The Result

Awake Fantasy Analyzer

By the end of the week, I had a working Fantasy Draft Analyzer—my first-ever AI-assisted product build. The speed and efficiency of AI let me focus on vision, product strategy, and refinement, while the heavy lifting of initial coding was accelerated dramatically.

I felt like Tony Stark creating new toys with Jarvis—designing, orchestrating, and iterating in real-time.


Key Takeaways

  • AI is powerful, but it’s not magic — it needs guidance, structure, and a clear vision to deliver meaningful results.
  • Experience matters — knowing the underlying engineering principles made me a far better “AI product manager.”
  • I have a product mind — this project reaffirmed my ability to see products not just as features, but as systems of interconnected building blocks.
  • Rapid prototyping is a game changer — with AI, you can go from concept to MVP in days, not months.

Final Thoughts

The Awake Fantasy Draft Analyzer is more than just a fun side project—it’s proof that AI can be a force multiplier for experienced professionals. The right mix of domain expertise, product vision, and technical understanding can turn a long-shelved idea into a live application in record time.

For me, this was the start of something bigger: using AI not just as a coding shortcut, but as a collaborative partner in product innovation.
