I'm a Product Manager committed to building the bridge between business strategy and the needs of the user. I specialize in turning complex challenges into clear, executable roadmaps, leading teams to efficient delivery and measurable outcomes that drive growth. That same sense of purpose and commitment to rigorous execution drives me outside the office, where I compete in Ironmans and other enduracnce races.

Case Study: PlayStella - From idea to MVP

An interactive daily game inspired by my cat Stella that challenges players to maximize their playtime with a moody tuxedo cat through quick reflexes and strategic decision-making

Discovery

Goal: To build a simple, sticky daily web game that demonstrates rapid prototyping and end-to-end product ownership.Hypothesis: A daily "mood management" micro-game based on simple risk assessment would drive high daily retention due to the time-gated, low-friction loop.The Problem I Solved: How to move from concept to a live, playable MVP in under 30 days while managing all development, content, and deployment independently.

Execution

Tooling Strategy: Leveraged Anthropic's Claude to generate the initial game logic/flowchart, content narratives, and mood-state transition prompts.Impact of AI: I do not have any coding experience. AI allowed me to focus my time on crucial PM tasks (UX/UI, deployment, and GTM strategy).The Refinement Loop: The AI output served as a "first draft." My role involved translating the conceptual artifact into functional code (HTML/JS) and refining the game state machine for balance and optimal user experience.

Go-to-Market & Metrics

Launch Strategy: Chose a simple GTM (Go-to-Market) strategy for the landing page and purchased playstella.com for a strong, memorable brand identity.Key Iteration (Post-Launch): Initial testing revealed users were confused by the random mood changes. Decision: Implemented a version where the emoji changes according to Stella's patience.Current Metrics (as of Nov. 1, 2025):
Since Oct. 25 (first deployment)
- Total pageviews: 460
- Total Unique Visitors: 283

Learnings

Lesson 1: The power of "Good Enough" AI: AI is a force multiplier for a one-person team. I learned how to move swiftly from AI-generated concepts to a high-quality production build, prioritizing speed over initial perfection.Lesson 2: Defining the Success Metric: With a daily game, Retention is the only metric that matters. All code and UX decisions were tied directly to maximizing the likelihood of a user returning tomorrow.
