Case Study

DevCoach

DevCoach is a full-stack learning platform that helps developers turn theory into practice by guiding them through real-world coding projects. It uses AI to generate project ideas, break them into achievable steps, and support users with hints and solutions while encouraging deep thinking.

Challenges

A key challenge was designing an experience that motivates developers to think independently while still offering support when they need it. This required developing a progressive guidance system without making the app feel like a tutorial.

Another challenge was enforcing fair use when using external AI APIs while maintaining a smooth user experience.

Solutions

I used Anthropic AI to generate project ideas and step-by-step breakdowns, and structured the interface to reveal hints and solutions gradually. This encourages users to try solving problems themselves before seeking help—mimicking how real developers work.

To manage costs, I implemented a credit-based access. Projects are protected behind user authentication using NextAuth, and data is stored in MongoDB for persistence and tracking.

Notable features

  • AI-generated project ideas tailored for individual developers
  • Step-based project flow with gated hints and solutions
  • Credit system integrated with Lemon Squeezy
  • Secure project access via NextAuth authentication
  • Real-time project progress tracking
  • Clean, responsive dashboard built with TypeScript and Tailwind CSS
